(1) "Department" means the department of public health.

(2)      "Diagnostic source assembly" means a diagnostic tube housing assembly with a beam- limiting device attached.

(3)       "Diagnostic type tube housing" means an x-ray tube housing constructed so that the leakage radiation at a distance of 1 meter from the tube target does not exceed 0.10 roentgen per hour under the following conditions:

(a)    For capacitor energy storage equipment when operated at is leakage technique factors.

(b)       For field emission equipment rated for pulsed operation when operated at its leakage technique factors.

(c)       For all other equipment when operated at 70 kVp and 10 milliamps or its calculated equivalent.

(4)     "Diagnostic x-ray system" means an x-ray system designed for irradiation of any part of the human or animal body for the purpose of diagnosis or visualization.

(5)     "Dose" means absorbed dose or dose equivalent as appropriate.

(6)     "Dose equivalent" means the absorbed dose in rads times certain modifying factors and is a quantity that expresses on a common scale for all radiation a measure of the postulated effect on a given organ from small amounts of radiation. The special unit of dose equivalent is the rem.
