Hello All,
Here is the input from Radiation Safety officer and Environmental Engineer of NIST, Boulder Laboratories:

Good morning; thanks for the additional info.

Since Stony Brook is located in NY, that state regulates x-ray machines. Their process is similar, including the paperwork.

Their x-ray website:

I would strongly urge your colleague to contact the Stony Brook Radiation Safety officer to ensure full compliance with all regulations and policies. They have two RSOs; this is the phone number for Sean Harling 631-632-9676.

If you need further help, let me know. Keep me informed on the outcome!

Hello Thomas,
Thank you for your time. This was regarding a query from Stony Brook University. I am a ACS member and also a ASR in CSD. Stony Brook University person wanted to get rid of the old X-ray equipment, which is equipped with Be window. She was worried about the toxicity of Be rather than other part X-ray tube. I will follow up and forward your mail with a copy to involved in the email with your permission of course. Information you provided is extremely helpful and a learning experience for all.
Let me if I can forward your email or just the information text?
Thanks a lot

Good morning, I will be glad to help based upon what I know regarding your circumstances.

I adopted the disposition system that Colorado uses as a means of due diligence which should minimize the chance of accidental exposures and the chance that unqualified personnel could operate the equipment.

See the following link for the form used to dispose of x-ray equipment:

As you can see, if you are merely using a 3rd party to transfer the equipment, then you provide contact information for the 3rd party.

If the intent is to dispose of the equipment directly as waste, then the machine must be made physically inoperable by dismantling the electrical circuitry such that the machine is not capable of producing radiation. Registrant must provide information on the method of disposal and the name and address of the landfill or recycling company. Please note that x-ray machines are considered electronic waste and must be disposed of properly.

If you need additional help, please call me. If you want further clarification on the disposal you can call the State; 303-692-3448 (Christine Irving, she has been there for a few decades). If she is unavailable, try her boss, Brian Vamvakias, at 303-692-3427.

Thanks! Sadly, this kind of collaboration is all too rare, and we don't have the new standard yet. The trade association representing non-ferrous foundries has challenged most aspects of the proposed standard, and asked for a hearing, which will delay things further. The work that goes into a new OSHA health standard is incredible. Materion and the USW submitted our recommended standard in February 2012. OSHA - quite rightly - can't cede its rulemaking authority to any outside parties, but their proposal was pretty close to ours. However, the text of the proposed regulation is 29 pages long. The detailed analysis of health effects, feasibility, economics, and possible alternatives that OSHA finally published this August is 910 pages long. All of that was necessitated by Congress and the Courts. The Agency accepted public comments up until November 5. They now have the job of analyzing and responding to all those comments, plus anything raised at the hearing. At best the final standard is a year away. All this is why, in the 45 years since the OSH Act was passed, OSHA has promulgated only 23 new health standards.

Mr. Wright;

This is super and is the way things should be. Congratulations to both the Steelworkers, Materion, and to OSHA.

Beryllium is transparent to most wavelengths of x-rays, so it is present in x-ray equipment in the form of x-ray windows. The best source for practical information on beryllium is Materion Brush, the only US producer of the pure metal, and the predominant supplier of beryllium alloys. They can go way beyond the regulatory information and give you good advice on the safety issues. In fact, the company has partnered with our union to advocate for a new, and much more protective OSHA standard. (And when's the last time you saw a company push for more stringent regulation of its major product?) The person to contact is Terry Civic:

Before disposing of old x-ray machines be sure to verify the capacitors and transformers are free of PCB's.

Hello All

If beryllium is in the powder form it is classified as hazardous waste and it should be disposed as hazardous waste. Since it is in a tube it should be disposed as hazardous waste as one disposes hazardous chemicals etc.

all the best
