Minimum total filter Operating kVp (Inherent plus added)

Below 50 kVp 0.5 mm aluminum 50-70 kVp 1.5 mm aluminum Above 70 kVp 2.5 mm aluminum

(5) A device shall be provided which terminates the exposure after a preset time interval or exposure. The exposure switch shall be of the dead-man type and where protective barriers are required shall be so arranged that it cannot be operated outside the shielded area.

(6) Each installation shall be arranged so that the operator can stand at least six feet from the patients, the X-ray tube and the useful beam during exposure.
