HAR §11-45-33. Shielding evaluation

(a) Before construction, the construction plans of all new facilities, or modifications of existing facilities, utilizing sources of radiation shall be submitted to the department for review and approval. These plans shall show, as a minimum, the following: (1) Normal location of the source of radiation; (2) General direction(s) of the useful beam for x-ray devices; (3) Locations of any windows and doors; (4) If the source of radiation is an x-ray device, the location of the operator's booth or position and the location of the control assembly; (5) Structural composition, dimensions, and thickness of all walls, doors, partitions, floor, and ceiling of room(s); (6) Dimensions and thickness of lead (in inches, millimeters, or nominal weight in pounds for a one square foot section) specified for walls, doors, partitions, floors, or ceiling of room(s); (7) Dimensions of the room(s); (8) Type of occupancy of all adjacent rooms and areas inclusive of space above and below the room(s) with sources of radiation; and (9) If there is an exterior wall, the distance to the closest area(s) where it is likely that individuals may be present. (b) The licensee or person intending to establish a facility or operation with sources of radiation shall utilize the services of a qualified medical physicist to determine the shielding requirements of the new facility or modification of an existing facility. A written shielding evaluation report by the qualified medical physicist shall be submitted with the architectural and electrical plans to the department as specified in subsection (a). The evaluation report shall include, but not limited to: (1) The anticipated workload or exposure from the source §11-45-33 45-48 of radiation; and (2) All basic assumptions used in the development of the shielding specifications. (3) All other relevant shielding specifications. (c) The shielding specifications on the construction plan shall be equal or greater than the shielding specifications identified on the qualified medical physicist's shielding evaluation report. (d) The approval of radiation shielding by the department shall not preclude the requirement of additional modifications should a subsequent analysis of operating conditions indicate a change in spatial relationship in the radiation facility or conditions which may be contrary to the requirements in subchapter 4. (e) A shielding evaluation before construction is optional for the following: (1) Dental facilities; (2) Podiatric facilities; or (3) Facilities determined by the department.
