AB - APPARATUS FOR THE CALIBRATION OF FILM DOSIMETERS IN ELECTRON RADIATION FIELDS OF HIGH INTENSITY V. A. Berlyand, V. V. Generalova, UDC M. N. Gurskii, and A. P. Zhanzhora In several technological processes, materials are irradiated with intense beams of 200-700-kev elec- trons. In such cases one must determine the dose absorbed in 100-500-/z-thick organic material layers. Film dosimeters can be used to measure the absorbed dose in rather thin layers and to determine the dose distribu- tion over the depth of the object irradiated. Overheating by the radiation in the case of high dose rates (up to 107 rd/sec), active media (ozone,radiolysis products), and the possible accumulation of space charge in dielec- trics [1] can substantially affect the dosimetric characteristics of film detectors. Therefore, when reliable results are to be obtained with film dosimeters, the dosimeters must be carefully calibrated with the aid of an absolute method, a calorimetric method, used under the real conditions of operation of the dosimeters. The authors of [2-4] have described several calorimeters that are used to calibrate films at electron energies in excess of 1 Mev. Little experimental work has been done on that problem at electron energies be- low 1 MeV. Some
