Studying the energy dependence of dosemeters

The results pf the investigation of energy dependence of detecting units sensitivity in the VA-F-18, 27012 (M 2300), DRG 2-01 and DKS-05 dosemeters used for dosimetric control at NPPs are presented. The dosemeters have several ionization chambers (not less than two), one of them with volume of 600-1000 cm3 is intended for measuring low radiation doses, i.e. for shielding quality control. The investigations are performed with reference devices reproducing exposure dose units, exposure dose rates as well as x and γ flux rates. The measurements have been performed using ionization chambers with volume of 1.5-100 cm3 at the 40-140 keV effective radiation energy
