Current through Vol. 41, No. 13, March 15, 2024

(a) For determining the doses specified in this section, a dose from x-rays up to 10 MeV may be assumed to be equivalent to the exposure measured by a properly calibrated appropriate instrument in air at or near the body surface in the region of the highest dose rate. In accordance with the provisions of 310:281-9-3(a), and except as provided in 310:281-9-2(b) and 310:281-9-3(c), no permittee shall use or transfer diagnostic x-ray systems in such a manner as to cause any individual in a restricted area to receive in any period of one calendar year from all diagnostic x-ray systems a total occupational dose in excess of the standards specified in 310:281-9-2(b).

(b) Rems per Calendar Year

(1) Total effective dose equivalent (TEDE) is 5 Rems;

(2) Deep dose equivalent (DDE) and committed dose equivalent (CDE) to any individual organ or tissue (other than the lens of the eye) are 50 Rems;

(3) Lens dose equivalent (LDE) is 15 Rems; and

(4) Shallow dose equivalent (SDE) to the skin or any extremity is 50 Rems.

(c) A permittee may permit an individual in a restricted area to receive a total occupational dose to the whole body greater than that permitted under 310:281-9-2(a), provided:

(1) during any calendar quarter, the total occupational dose to the whole body cannot exceed 3 rems;

(2) the permittee has determined the individual's accumulated occupational dose to the whole body on a form provided by the Department or on a clear and legible record containing all the information required in that form and has otherwise complied with 310:281-9-3. As used in this subsection, "dose to the whole body" includes any dose to the whole body, gonads, active blood-forming organs, head and trunk, or lens of eye.
