Solid Waste Management Program fact sheet
Division of Environmental Quality Acting Director: Steve Feeler

This fact sheet provides guidance for medical, veterinary, dental and numerous other facilities who must dispose of old x-ray equipment.

First, it is important to note that x-rays are produced only when the equipment is energized and there is no radioactive material in the equipment that can produce radiation. There are no radiation hazards if the x-ray equipment’s electrical power is turned off or disconnected.

Be Aware: There is no radiation hazard associated with old x-ray equipment, but there are potential disposal issues. Some older x-ray equipment (manufactured prior to July 2, 1979) may have cooling oil around the x-ray and rectifier tubes that contains polychlorinated biphenyls (PCBs). This oil was used in some x-ray equipment transformers, tubes and capacitors to aid in insulation. This is considered a hazardous waste if the amount of PCBs are above a certain level. If your equipment is one of these older models with PCBs, there could be a disposal problem.   An x-ray service company may be able to advise you on whether your equipment contains PCBs.

If you are trying to dispose of this type of equipment, you should contact the Missouri Department of Natural Resources, Hazardous Waste Program for guidance at:

There are several ways in which the registrant may dispose of radiation-producing equipment which do not contain PCBs:

Missouri law also requires that all radiation-producing equipment is registered with the Missouri Radiation Control Program (MRCP) within the Missouri Department of Health and Human Services (DHSS) regardless of the usage status (i.e., operational, not-in-use, etc.). Registration status will only be terminated when a registrant no longer possesses the radiation-producing equipment.

When a registrant is no longer in possession of radiation-producing equipment, transfers possession, or renders the equipment nonfunctional, the registrant must notify the MRCP in writing. These links provide additional information from the DHSS on this topic:
