The Radiation Post



Disposing of Radioactive Waste

Ideally, any industry, university lab, manufacturing plant, medical facility or nuclear power plant should have a Radiation Safety Officer and established safety plan for disposing of radioactive waste. Failure to do so has disastrous effects on plants, animals and humans who are unknowingly exposed. Take, for instance, the city of Goias, Brazil – where robbers stole a radioactive machine from an abandoned hospital and unwittingly poisoned 250 people who were unknowingly exposed – four of whom died.

It’s imperative that nuclear and radioactive materials are disposed of properly. If you are at all unsure of what you should do with radioactive materials – including gloves, sleeves, paper or glassware exposed to radiation – contact your Radiation Safety Officer ASAP for specific instructions.

The bottom line is that while it may seem like radioactive products and materials are “disposed of” they aren’t; radioactive isotopes have half-lives and many continue to emit radiation for hundreds to thousands and thousands of years. So, until the scientific innovators find a more successful solution, these toxic items are removed and stored far away (hopefully) from where they can seep into ground water, surrounding soil layers and the environment.

Most common methods of disposing of radioactive waste

After contaminated materials and/or radioactive substances have been disposed as per your company’s safety plan, it is disposed of in one of multiple ways.

On-site disposal and treatment

Initially, your company safety plan will incorporate things like specially marked boxes to house contaminated paper, glassware, sleeves, gloves, etc. Sharps containers are provided for knives, syringes, blades, broken glass and so on. Finally, special sinks or flushing stations are used for liquid waste.

In many cases, radioactive waste is temporarily treated onsite to mitigate its effects until it is more permanently disposed of. On-site treatments typically consist of processes such as vitrification, ion exchange or synroc. Again, on-site treatment isn’t the end of the line, but it prepares radioactive materials to be transported and minimizes the risk of short-term damage.

Incineration

Common in the medical arena – including labs and hospitals – low-level waste is incinerated at extremely high temperatures. This renders it neutral or to such low-risk levels that the incinerated waste can be disposed of in landfills just like everyday trash.

Geologic disposal

This is by far the most common method of storing nuclear and radioactive waste. Unfortunately, there are very few approved nuclear disposal sites around the world – a reason that there are nearly 30,000 undisposed-of tons of ceramic uranium dioxide pellets, stored in metal rods, at nuclear power plants around the world.

Geologic disposal directly translates to digging big pits, lining them with barriers that prevent radioactive seepage and burying radioactive waste deep into the ground. Before being buried, most of this mid- to higher-level waste is solidified in concrete or bitumen to further diminish its potency.

Transmutation

The idea behind transmutation is that potent radioactive isotopes are transformed into less-potent versions, making them somewhat safer to store and decreasing their half-life. For example, chemical reactions where protons hit a particle and change it. The most common examples of this happening now are transmuting chlorine into argon.

Theoretical disposal options

Then there are some proposed suggestions for disposing of radioactive waste that aren’t put into practice yet. These include:

  • Reprocessing: Often, radioactive waste is an amalgam that includes non-radioactive components. Reprocessing these to remove usable components (fissionable) from non-useable components that are then disposed of. Overall, this decreases the mass of the waste.
  • Disposal in space: Some experts feel we should build specialized rockets that would be loaded with our radioactive waste and then shot up into outer space. This option is heavily contested, with opponents citing the exorbitant financial costs, the potential for pre-space explosions to create a nuclear cloud for which there is no containment method and long-term ethical considerations.

There is no doubt that the U.S. and the world at large lacks enough disposal sites and methods to handle the current level of radioactive waste. This is of major concern to everyone across the nuclear and radiation industries.

Potassium Iodide, Your Thyroid & Radiation Protection

There are people all over the world who keep non-expired doses of potassium iodide on hand to protect themselves in the case of a nuclear fallout or related radioactive disaster. They do this as a proactive way of protecting themselves in case a nuclear emergency involves the presence of radioactive iodine – frequently released in a cloud or plume into the air, after which it settles on the ground, contaminating everything it touches – including food sources.

By taking potassium iodide, only if advised to do so by health and safety officials, you can “block” the thyroid’s ability to uptake the radioactive version, minimizing the after affects.

Why is the thyroid so important?

When you think of radiation poisoning or the eventual cancers and other diseases associated with former radiation exposure, it may seem strange that the thyroid is the gland healthcare officials focus on and protect. However, the thyroid gland – a two-inch, butterfly-shaped gland located at the front of the neck, below the Adam’s apple – is a powerhouse; the human body doesn’t fare well when thyroid function is below par.

The thyroid gland is responsible for hormone production and your body’s metabolism, so when it is negatively impacted, you can experience issues pertaining to:

  • Overall metabolic rate
  • Digestion
  • Heart function
  • Muscle control
  • Moods
  • Fertility
  • Bone maintenance
  • Brain development

Iodine – found in certain foods and added to “iodized salt,” is an essential nutrient to the thyroid. During normal life, and with a healthy diet, the minimum amount of iodine the thyroid requires is assimilated via the foods you eat. Any lack of iodine can result in thyroid issues.

The thyroid can’t distinguish between radioactive & non-radioactive iodine

Because the thyroid only requires a fairly minimal amount of iodine to thrive, it has a threshold of sorts. Once it has absorbed all the iodine it can from the bloodstream, it stops absorbing it. However, the thyroid doesn’t have the ability to distinguish between radioactive iodine and non-radioactive iodine.

In the event of a nuclear disaster that releases radioactive iodine, taking the recommended doses of potassium iodide (non-radioactive) saturates the thyroid gland, serving as a radiation “blocker” since the thyroid will leave the radioactive version that’s then excreted by the body.

Also important to note: good ol’ fashioned soap and warm water, combined with a thorough and vigorous scrub, are enough to eradicate radioactive iodine that has settled on the clothes (best to discard altogether or launder repeatedly), skin, hair, etc. Read, How do You Stop A Radioactive Spill, for more information on that. While the post is targeted to industrial and chemical industries, the basic tenets apply to anyone exposed to radioactive fallout.

When should you take potassium iodide (KI)?

Potassium Iodide (KI) is the same type of iodine used in table salt. That being said, KI is added in such micro-doses to table salt that ingesting copious amounts of iodide salt will not help to protect you from radioactive iodide. In fact, the World Health Organization warns, “…iodized salt should not be used as a substitute for KI since it will not provide protection against radioactive iodine, and eating excessive amounts of iodized salt will itself pose a significant health hazard.”

Potassium iodide can be purchased in supplement form without a prescription. KI should only be taken upon recommendation of health and safety officials immediately preceding or during a nuclear event – and should never be taken as a precautionary supplement as that can have adverse health effects.

It’s best to purchase KI from regulated and approved agencies. At this point, the US Government currently backs the quality of four different KI products:

  • iOSAT tablets, 130mg, from Anbex, Inc.
  • ThyroSafe tablets, 65mg, from Recipharm AB
  • ThyroShield oral solution, 65mg/mL, from Arco Pharmaceuticals, LLC
  • Potassium Iodide Oral Solution USP, 65mg/mL, from Mission Pharmacal Company

Visit the CDC’s website page on Bioterrorism and Drug Preparedness for information about dosage (based on age, weight and the measured level of radioactive iodide exposure), when you should begin taking KI and for how long, who should avoid taking the supplement, adverse side effects/risks, etc.

KI doesn’t provide comprehensive radiation protection

It’s important to note that KI isn’t a comprehensive radiation shielding product, it only protects us from radioactive events that release radioactive iodide. It does not protect you from:

  • Any other radioactive materials, such as radioactive caesium
  • Surface radiation (it doesn’t protect you from exposure to radiation on your skin, the ground, etc.
  • Ingesting or absorbing radiation, it simply protects the thyroid gland from absorbing it, which goes a long way toward protecting the body’s basic physiologic functions.

More comprehensive radiation protection and shielding products are required to protect your body, lungs, and external body from radiation exposure.

What is a Radiation Safety Officer

Any company or business requiring employees to work with or around radiation and/or radioactive materials should have a clear Radiation Safety Program in place, and that program is traditionally led by a designated (qualified) Radiation Safety Officer. If your company is registered with the Nuclear Regulatory Commission (NRC), you are required to have a designated Radiation Safety Officer – and the designation must be in writing.

This designation requires both a certain level of education, knowledge, training and credentials. Different employers and HR department have different guidelines or requirements – with hospitals and universities typically requiring a college degree in a scientific or technical field as well as a number of years of radiation safety training.

Also, only regulatory agencies can “pronounce” you a radiation safety officer. So, no matter how great a job you may have done at your place of employment overseeing RSO-related duties, and even if your boss says you’re the RSO, you’ll need to write a letter to your state’s regulatory agency, requesting official designation. This letter should include and/or attach your diploma, qualifications/certifications, proof of any RSO training you’ve had, work experience/training, etc.

radiation safety officer

Who is the Radiation Safety Officer?

Depending on the size of your company, the radiation safety officer (RSO) may be a full-time position in and of itself; smaller companies may have a key management person or safety manager take on the responsibilities of an RSO, above and beyond their regular weekday duties and job responsibilities.

Optimally, medium- to large businesses have a radiation safety committee, and the RSO supports that committee in its duties and serves on the committee, often in the capacity of secretary and record keeper.

What Does the RSO Do?

As part of overseeing the company’s radiation safety program and training, a radiation safety officer is responsible for:

  • Performing an annual review of the company’s radiation safety program and adherence to ALARA for the year.
  • Compiling quarterly reports of occupational/personal worker exposure to radiation for the quarter.
  • Putting together a quarterly compilation of radiation levels in both restricted and unrestricted areas, comparing them with previous quarters and ensuring they were at ALARA levels.
  • Organize and schedule regular briefings, trainings and educational sessions that instruct employees about radiation safety and the ALARA program(s) put in place.
  • Investigate and report on any instances where radiation exposure was over and beyond the maximum acceptable levels.
  • Ensure that all actions and/or incidences related to radioactive materials and radiation exposure take place within and under regulatory guidelines at both the federal, state and local levels.

While many of these tasks can be delegated and overseen by the RSO and the Radiation Safety Committee and/or safety management team, the ultimate responsibility and liability rests on the RSO’s shoulders.

Training Required for RSOs

Again, requirements vary – with some companies requiring a PhD in nuclear physics, and others requiring a high school diploma and ample radiation safety training.

There are varying levels of coursework, education and training required to become an RSO. The most basic training and certification includes completing and passing a 40-Hour RSO Short Course. However, the size and complexity of your company’s interactions with radioactive materials dictates how much training and experience are required.

Ultimately, RSO’s lead the education and training (not to mention safety program) at their places of work, and that means having sufficient knowledge and experience to teach and train employees and staff regarding:

RSO’s do a tremendous amount of record keeping and safeguarding sensitive files so organizational skills as well as discretion are essential character traits.

How Much do RSO’s Make?

There is no once salary fits all answer to the question of how much RSOs make. The larger the employer, the greater your qualifications, the higher your salary. With that being said, work.chron.com cites that RSO’s with PhDs in nuclear engineering can make as much as $180,000 per year, with the average salary hovering right around the $134,000 mark. On the other hand, those with a master’s degree earn around $126,822, and those with a bachelor’s degree earn closer to $124,161.

Then again, if you work for a smaller company and/or your RSO duties are adjunct to your regular responsibilities, you may earn as low as $66,000 or so.

What is a Dosimeter?

Ionizing radiation is harmful. At best, it causes radiation sickness and/or burns; at its worst, it’s fatal or is the cause of terminal cancers and other health conditions that can be fatal. Fortunately, radiation dosimeters come in various sizes and styles, but are ultimately designed to measure the levels of harmful ionizing radiation as a safety precaution.

Smaller models can be worn by those working in radioactive environments to monitor their exposure in real-time, as well as to keep track of cumulative exposure overtime, since slow and continuous exposure to low-dose ionizing radiation is as harmful – or more so – than acute, high doses in a single exposure. They are a standard tool in radioactive industries and careers, as well as in the disciplines of radiation dosimetry and radiation health physics.

what is a dosimiter

What is a Dosimiter and How Does it Measure Radiation?

These devices are made using radiation sensitive materials to measure exposure to gamma radiation, x-radiation and high-energy beta radiation (such as P-32). In addition to measuring and recording whole body doses, some dosimeters are designed to measure immediate, localized, radiation exposure.

The types worn by employees or personnel working in and around ionizing radiation exposure are called radiation badges, and can be clipped onto their protective clothing. Radiation dosimeters are most commonly worn and used by those whose work puts them at risk for maximum exposure limits:

  • Occupational whole body dose limit is 5,000 millirems per year
  • Dose limit to the extremities (hands, fingers, etc.) is 50,000 millirems per year

Professionals and employees most likely to use and/or wear a radiation badge include:

  • Nuclear power plant workers
  • Radiographers
  • Physicians working in the field of radiotherapy
  • Laboratory staff using radioactive materials
  • HAZMAT teams when called to nuclear disasters and/or to investigate suspected cases of harmful occupational radiation exposure

It is important to note that while dosimeters measure radiation exposure, they do not protect the wearer from the exposure and are not considered radiation shielding.

5 Types of Radiation Dosimeters

There are five different types of radiation dosimeters.

  1. Electronic Personal Dosimeter (EPD). These personal electronic devices are most often used in scenarios where there is high dose radiation exposure, and where employees are only working within those high exposure limits for a short time. EPDs have several sophisticated functions and can be reset after taking a reading – which is recorded – for reuse.
  2. MOSFET Dosimeter. These are used as clinical dosimeters in order to measure the radiation levels of radiotherapy radiation beams. MOSFET dosimeters provide readings within extremely thin active areas and are very small in size. The dosimeter’s post radiation signals are permanently stored.
  3. Film Badge Dosimeter. These tools are designed for one-time use, after which they are no longer functional. Radiation level absorption is shown via changes in the film emulsion and is evident after the film is developed.
  4. Quartz Fiber Dosimeter (QFD). QFDs are the precursors to EFDs and are now being superseded by them. Also designed for one-time use, QFDs are charged to a high voltage and readings are taken in response to the changes in electrical charge, which is proportional to radiation exposure levels.
  5. Thermoluminescent dosimeters (TLD). This type of dosimeter uses a crystal that emits light when exposed to heat, caused by radiation exposure. The intensity of the visible light is measure, indicating the level of exposure. As with EFDs, TLDs are being used more and more in place of QFDs.

Dosimeters Are and Essential Part of Radiation Safety Programs

Ultimately, dosimeters and radiation badges are essential parts of any company’s radiation safety program, and should be used regularly, and diligently, as per manufacturer’s recommendations to keep worker’s radiation exposure well below maximum levels. Dosimeters should be used in compliance with industry best standards, as well as all the necessary radiation shielding and protective clothing products used to keep employees safe.

Radioactive Holiday Gifts For the Ones You Love (and hate)

Tired of buying the same ol’ holiday gifts year after year? Looking for that truly rare, one-of-a-kind present for the impossible to buy for relatives in your life? We have just the thing – radioactive elements.

We’re joking (sort of). Believe it or not, there was a time when radiation was considered good for you – and nobody understood just how serious the effects of long-term radiation exposure really were. As a result, there were plenty of radioactive items for sale in everything from housewives’ magazines, to the Sears & Roebuck catalog and even the corner drugstore.

radioactive_gift_web

Real Live Examples of Radioactive Household Items & Gifts

Imagine finding one of these gifts under your holiday tree or as the result of your dreidel spin.

  1. Radioactive face cream. Women the world over were excited to try a range of Tho-Radia cosmetic products, including face creams, lipstick, perfumes, and powders. Why wouldn’t they when the radioactive ingredients promised to enhance your youthful glow. Fortunately, this makeup didn’t stay on the market for very long.

  2. Doromad toothpaste. If you lived in Germany between the years 1940 and 1945, you may have been the proud owner of Doromad toothpaste. This paste contained radioactive thorium, which was marketed to make teeth glow a little brighter and whiter….before they fell out, we would imagine. The good news is thorium was added in minimal amounts. The bad news is that users ingested and absorbed low-doses of radiation as for the duration that they used the products, and we won’t even think about the radiation that was going down drains into sewers, storm drains and groundwater supplies.

  3. The Atomic Energy Lab for the kids! Of all the radioactive products that were given as holiday gifts, this one is the most bittersweet. Well-intentioned parents who gifted, atomic scientist children their very own Atomic Energy Lab had their hearts in the right place. Created during the 1950s by the same guy who brought us the infamous Erector Sets, the Gilbert U-238 Atomic Energy Laboratory introduced children to basic radioactive elements and the experiments to show them off. It even included its very own Geiger counter. Unfortunately, children and parents who purchased the lab are not eligible for Radiation Exposure Compensation.

  4. Radiation for arthritis relief and erectile dysfunction. When radioactive isotopes were first discovered, there was no lack of advertised health wonders attributed to them. One example of this is Radithor, with a subheading that read, “The modern weapon of curative science.” Well, that was certainly the truth. The radioactive water was infused with Radium-226 and 228 isotopes. Unfortunately, true believers suffered serious side effects, such as famous socialite and athlete Eben Beyers. Mr. Beyers was a big consumer of Radithor and was reported to have consumed 1400 small bottles of the stuff (before you scoff – add up the number energy drinks your fellow countrymen consume each day). After a couple of years, he became extremely ill, had to have parts of his mouth and jaw removed, and eventually died.

  5. The first luminescent watches. The glow-ability of certain radioactive elements wasn’t lost on commercial giants. Hence, in the early 1900s, certain watchmakers used a radium-based dye to paint the numbers onto the watch faces so they would glow in the dark. Again, unfortunately, without an understanding of how dangerous radiation exposure was (no ALARA awareness back then), many of the women who painted the digits fell ill, were disfigured and many eventually died because they habitually licked the brushes to smooth the bristles in between paint strokes.

So that’s the reality of life before radiation awareness. Fortunately, times have changed.

Real Radiation-Themed Holiday Gifts That Won’t Make Your Parts Fall Off

If, however, you have a person on your gift list who might like a little laugh, we do have a few radiation-themed suggestions for you.

  • Tee-Shirts and Onesies. The famed site, Cafepress, has a wide range of T-shirts, hoodies, tote bags and even onesies with radioactive symbols and clever messages. Some of them even glow in the dark, sans any threat of radiation.

  • A Glow-in-the-Dark Coaster Set. This is probably the best crowd pleaser of the bunch, and one of our personal favorites. The team at ThinkGeek created a glow-in-the-dark coaster set. Each square is modeled from the radioactive elements on the periodic table, consisting of Radium-226 (Red), Plutonium-244 (Blue), Uranium-238 (Green), and Thorium-232 (Orange).

  • Radiation Hazard Fallout Keychain. We’re also fans of this Radiation Hazard Fallout Keychain sold on Etsy. It’s handmade, using a high-definition decal, covered with a dome crystal glass, set on an antique bronze-finished housing.

Those of us here at LANCS wish you and your family a very happy, safe and radiation-free holiday season.



Working With Radiation: Wear the Right Protective Clothing

You can never be too cautious when you work with or around radiation and radioactive products. While there’s no need to wear a protective hood when speaking on your cell phone (not yet, anyway), companies and employees who work in a radioactive environment or with radioactive products should always err on the side of caution and invest in high-quality protective clothing.

protectiveimg1

Is Your Company Providing the Right Protective Clothing to Prevent Employee Radiation Exposure?

ALARA regulations are very clear that it is the employer’s responsibility to ensure their employees are 100% aware of the risks of work-related radiation potential as well as which scenarios put the employees at risk of radioactive exposure. Also, employers must make every effort possible to protect their employees from exposure to radiation, using specifically design products, like radiation shielding materials, glove bags or sleeves and/or appropriate protective clothing.

The following are examples of protective clothing, designed to shield the wearer from harmful radiation exposure.

Full-Protection Suits. For those who are surrounded or working directly in an environment that offers little to no shielding, workers should be provided with fully protective suits. These suits range from one-piece to two-piece suits and including wet suits. They are available in a variety of styles and price points. Some models include pocket dosimeters so workers can keep a closer eye on their exposure level.
Many of the full-protection suit models come with options such as attachments for hoods and booties, additional exhaust vents and options for zipper or Velcro openings. Our suits are available in S, M, L, XL, XXL and XXXL.

Welder Jackets. Your welders will appreciate the custom welder jacket, which provides additional protection – especially around the shoulders where protective suit seams can invisibly wear over time. It will also shield workers from radiation exposure due to general rips and tears, which are more common on the upper body. Our welder jackets provide radiation protection from the neck to the wrists and are available in sizes M to 3XL.

Hoods. The one-size-fits all hood comes in three different style options and materials: PVC, cotton and urethane. All have a Velcro-front closure.

Booties, Shoe Covers and Sleeves. In addition to the risk posed to employees who work directly with radiation, there is always the risk of contamination from one work area to another, or from work to home. Booties, shoe covers and sleeves are one of the best mechanisms for preventing contamination and cross-contamination scenarios. Our shoe covers range from those that cover the shoe only, to full- high-top booties and cotton overshoes for maximum protection. We offer both regular sleeves as well as chemical sleeves, the former meets the requirements of MIL-A-24914.

You can see our full array of protective clothing on our website. Are you looking for more specific or customized protective gear, shielding or clothing? Contact Lancs Industries where our experience and industry longevity make us one of the best manufacturers of rote and custom radiation shielding world-wide.



Portable Containment Tents : Safety and Efficiency

Does your workplace or industrial facility require the use of radiation, lead or other harmful contaminants? If so, portable containment tents are an affordable and efficient solution for preventing the spread of contaminants from surface to surface, or into the surrounding environment, and they also minimize the scope and complexity of your cleanup process.
In addition to creating a safer and healthier workplace, portable containment tents can be specially designed and fabricated to meet your needs.

Lancs_containmenttent

The Benefits of a Portable Containment Tent

There are a range of products designed to prevent the cross-contamination by radiological or other hazardous materials. Portable containment tents are some of the most desirable and convenient options for several reasons:

1. They’re portable! Not surprisingly, ability to transport, set up and break down your portable containment tent in a range of areas, and within a reasonable amount of time, is one of their most desirable benefits. Portable containment tents can be used throughout your facility, depending on the task at hand. They can also be transferred from facility to facility or to off-site locations when necessary.

2. Quick and easy to set up. When using the tent for an off-site or outdoor location, portable containment tents are relatively quick and easy to set up. In many cases, the alternative to a portable containment tent is a hard-sided trailer version. These must be able to be trucked in and unloaded, which isn’t always possible depending on the area or terrain available to you.

3. They are lightweight and compact. Unlike hard-sided and more permanent options, portable containment tents are constructed from lighter-weight, plastic materials“. Our portable containment tent walls and ceilings are made from Pacifitex 1400. The floors are constructed from Pacifitex 1800 for added durability. Frames are built from 1 inch nominal Schedule 40 galvanized steel pipe, which are incredibly sturdy but light enough to be easily handled and assembled. Together, these materials make for a finished product that is compact enough to be transported easily and light enough for a small team to assemble with a minimum of additional equipment.

4. Designed to your specifications. While prefabricated containment tents are available in a variety of sizes, ranging from smaller, single-chamber versions to larger dual-chamber options, they can also be designed and built to order. If you are newer to the portable containment tent market or have an unusual job to complete, our team can draw from a longstanding history from which to make suggestions and to design a tent that will work best for your company’s particular needs and wants.

5. They are affordable. Per unit, portable containment tents are more affordable than hard-sided or trailer versions with similar dimensions and features. This is true even with the inclusion of the accompanying ventilation and filtration units.

Once your job is complete, proper attention to post-work clean-up will render your portable unit contaminant free, ready to be packed up and moved to the next job on your list or easily stored until the next time you are in need of a tent, decon chamber, steam generator work tent or roofless bull pen containment.

Would you like to learn more about your portable containment tent options? Contact the team at Lancs Industries and we’ll be happy to answer your questions or provide more information about our radiation and nuclear shielding products.



Glovebags for Radiological Work on Piping and Valves

Lancs1

During the planning for radiological work on piping and valves, one of the options is to consider the use of a glovebag. Many people think that glovebags take too long or are too difficult to install. Lancs glovebag models LI-304 and LI338 have a continuous Velcro strip that allows the worker to wrap the glovebag around the pipe or valve, install any tools, seal the Velcro and then tape each end.

The LI-304 and LI-338 glovebags are the same shape, just different dimensions. The LI-304 is 18” in diameter by 24” long. The LI-338 is 24” in diameter by 36” long. Once the Velcro is sealed it should be secured by gluing a patch over the Velcro or taping it securely. Some facilities apply a sealant such as RTV to the Velcro before it is squeezed together. Sealing the Velcro is a work practice that ensures airborne contamination in the glovebag will not escape, since the Velcro closure is not air-tight. The installation should only take a few minutes. Lancs can make these glovebags in any size and install accessories including waste sleeves, HEPA filter sleeves, or drain connections.

Lancs2person

There were at least two incidents at power plants involving the spread of contamination when workers performed grinding on the inside of piping. In each case, the pipe had been cut and was being groomed by workers for a butt weld. The grooming involved the removal of debris and corrosion near the end of the pipe. This was done by workers using a motorized wire brush or flapper wheel. Once the oxide layer on the inside of the pipe was disturbed, the fixed contamination became loose and was spread throughout the work area and on to the worker.
Lancs2chart
The Lancs grinding glovebag was developed by Lancs working with personnel from the Palo Verde Nuclear Power Station. The glovebag installs quickly and allows the worker to groom the pipe without spreading contamination. Once the grooming is complete, the glovebag can be untapped and slid off the pipe. Lancs can make this glovebag in whatever size you need.



INTRODUCING THE LANCS QUICKRACK

QuickRack_Product

Glovebags Training at Dresden Nuclear Power Station

LancsDresdenBlog
Recently, a Lancs team visited the Dresden Nuclear Power Station and provided training on the use of glovebags. The plant is in the process of removing several tanks and associated piping. The larger 8” diameter piping will be cut out using an E.H. Wachs split frame cutting machine inside a Lancs “Dog House” glove bag.

See more Lancs glovebags here.
