the exposure rate depends to a considerable extent on the tube voltage

(2) For the purposes of subsection (1), the air kerma or exposure rate must be determined at a location along the X-ray beam axis that is

Radiation exposure can be roughly estimated by measuring the exposure rate (in µSv/h) delivered at a distance of 1 meter from a source of one MBq.

for small-format, low-intensity radioscopic equipment, to the distance at which the equipment delivers an air kerma rate of 50 mGy/min or an exposure rate of 5.75 R/min.

(iv) for small-format, low-intensity radioscopic equipment, to the distance at which the equipment delivers an air kerma rate of 50 mGy/min or an exposure rate of 5.75 R/min.
