Abstract : The experiment studied the effects of exposure rate on the response of the following gamma dosimeters: silver-activated metaphosphate glass plates and rods, lithium fluoride and manganese-activated calcium fluoride microthermoluminescent dosimeters, and cobalt-activated borosilicate glass plates. Data was obtained in the exposure range of approximately 1,500 to 45,000 R at exposure rates from 5.2x10 to the 10th power R/s to 2.2x10 to the 11th power R/s. The results of this experiment indicate that no differences exist in the relative responses of the various dosimeters that may be attributed to exposure rate or to an interaction between exposure and exposure rate. No absolute exposure measurements were made, therefore data were analyzed on a relative basis. (Author)
