This program applies to all individuals and/or departments using analytical or diagnostic instrumentation that produces x-ray radiation either directly or indirectly in the course of work. This includes bone densitometers, electron microscopes, diffractometers and CT-scanners in addition to traditional x-ray imaging equipment.


All equipment purchases must be placed by an authorized user and approved by the RSO prior to ordering. All instruments must be inspected and certified before use and all personnel involved, trained accordingly. Certification and training requirements vary by instrument type and procedures implemented. Those instruments used in the healing arts (conventional medical x-ray machines) must be certified by a state qualified expert and records maintained as per Virginia Department of Health (VDH) regulations. For all other x-ray instrumentation, inspections are conducted by EHS personnel and records shared with VDH as requested. Further details and information are given in the written program
