Investigation of the energy dependence of dosimeters

This paper reports on the results of investigations of the energy dependence of the detectors in the VA-J-18, 27012 (M 2300), DRG-01 and DKS-05 dosimeters. Each of the dosimeters is provided with several ionization chambers; one of the ionization chambers with a volume of ca 600-1000 cm/sup 3/ is designated for measuring low radiation levels, i.e., for monitoring the quality of radiation shields. The investigations were made on reference units reproducing the unit of the exposure dose, the exposure dose rate, and the energy flux of x-ray and gamma radiation. The parameters of the instruments examined are presented. The instruments can be used as reference means of measurements and the error of dosimetric measurements can be reduced as the reliability of the instruments has been increased.
