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.

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.
