Examples of radiation machines include:
- Cabinet X-ray units
- Veterinary X-ray machines
- X-ray: crystallography; diffraction; and fluorescence units
Prior to surplusing, the authorized user must attach a completed Item Evaluation form listing:
- Specific radioactive material(s) which caused the contamination;
- Any decontamination method which was used;
- Any component capable of producing radiation which has been disconnected or removed from the equipment item. See below.

Special Clearance Procedures
Radiation machines require special clearance procedures prior to collection by Surplus Stores. See SPPM 9.22.
Contact the Radiation Safety Office before making arrangements for movement of this type of equipment; telephone 335-8916.
The authorized user is to disconnect or disable the X-ray tubes on all radiation machines which are offered for surplus as scrap or off-campus for X-ray uses. See SPPM 9.22.
A tube may remain with the machine in the event of possible reuse. It is the responsibility of the purchaser to reconnect the tube.
If the equipment is to be used in the state of Washington, the purchaser is also responsible for notifying the Department of Health, Radiation Protection Division by telephone at 1-800-299-9729. (WAC 246-224-0020).
- Surplus Stores must inform the RSO of the identity of the purchaser of the X-ray tube.
Surplus Stores completes Section 2 of the Notification of Change in Responsibility for a Radiation Machine and submits the form to the RSO. See also below.
- The RSO must, in turn, inform the Washington Department of Health (DoH) X-ray Program of the identity of the purchaser within fifteen days of the date of sale.
