(q) Only an individual required for the radiographic procedure may be in the radiographic room during exposure and, except for the patient, no unprotected parts of the individual’s body may be in the useful beam. (r) The useful beam must be restricted to the area of the image receptor, and evidence of beam edges must show up on at least three sides of each radiographic image, except where a properly functioning positive beam limiting device is in place. (s) A patient must be provided with a shield to protect the gonadal area of the body, unless the use of a shield prohibits a proper diagnosis. (t) A protective apron and gloves must be tested at least annually to verify the continued integrity of radiation shielding properties sufficient to meet the standards of 7 AAC 18.440( l). (u) A chest photofluorographic installation does not meet radiation safety requirements and may not be used. (v) Mobile diagnostic radiographic equipment must meet the requirements of this section, except for the
(1) provisions of (q) of this section, if
(A) all individuals, except the patient being examined, are in shielded positions during exposure; and
(B) personnel monitoring is required for all individuals operating mobile x-ray equipment; and
(2) shielding requirement of (f) of this section, except that if a mobile unit is used routinely for more than 30 days in one location, the unit is considered a fixed installation subject to the shielding requirements specified in this section and 7 AAC 18.430. (w) A registrant who uses film imaging and processing of the images shall establish processing quality control procedures at regular intervals that at least include
(1) documenting chemical change dates;
(2) documenting developer temperatures;
(3) processing a test strip that may be read by densitometer once weekly;
(4) documenting that chemical replenishment rates are maintained within plus or minus 15 percent once weekly;
(5) documenting that fixer retention does not exceed 0.05 milligrams per centimeter; and
(6) performing a two-minute fog test that demonstrates an optical density of no more than 0.05 on film used for imaging individuals or a step wedge image that does not change more than one step, annually or following any changes in the structural integrity of the darkroom.
