  2. GENERAL RULES - X-RAY MACHINES • All operating personnel must be intimately familiar with the principles of operation, principles of radiation safety, and potential general and specific hazards of their particular machine. • Radiation surveys must be made: • annually • whenever beam‑target or specimen‑detector geometry is changed • whenever shielding arrangements are altered • after maintenance work.

  3. GENERAL RULES - X-RAY MACHINES • Master‑switch keys and secondary keys should be in the possession of the first person entering an exposure room, and that person should be the last to leave the room. • Situations which require interlocks to be temporarily disabled require prior approval of the campus Radiation Safety Officer.

  4. GENERAL RULES - X-RAY MACHINES • All radiation producing equipment must have clearly visible warning lights to indicate when the equipment is generating radiation. Additional caution lights are recommended as a redundant system for showing the machine status. Warning light systems should be configured to indicate when a light is not operational.

  5. GENERAL RULES - X-RAY MACHINES • All operating personnel must be properly badged with individually assigned integrating dosimeter devices. • Approved warning signs indicating the nature of the hazards must be posted at entrances to hazard areas, and the instrument console must be posted with a plaque indicating the nature and quality of the radiation produced.

  6. GENERAL RULES - X-RAY MACHINES • Unusual operations or unexpected machine behavior must be reported to the campus Radiation Safety Office immediately.
