MAYAK FILM DOSIMETER RESPONSE STUDIES, PART II: RESPONSE MODELS

A study was performed of energy and angular responses of the film dosimeters that were used for worker monitoring at the Mayak Production Association (Mayak PA) in 1948–1992. The study used experimental data from tests with three types of individual film dosimeters, and the data were used to determi...

Description
Summary:A study was performed of energy and angular responses of the film dosimeters that were used for worker monitoring at the Mayak Production Association (Mayak PA) in 1948–1992. The study used experimental data from tests with three types of individual film dosimeters, and the data were used to determine the dosimeters’ energy and angular response characteristics in the range from 9 keV to Co energies, with the dosimeters exposed both free-in-air and on-phantom at horizontal and vertical rotation. Mathematical models of the dosimeters were developed to calculate the response characteristics of the dosimeters. The models of the film dosimeters were validated by comparing calculations to measurements. The models were then used as the basis for individual dose reconstruction in realistic photon spectra and worker exposure geometries at the Mayak PA workplaces. Reconstructed individual doses have been included in the Mayak worker database “Doses-2005” that is used for epidemiological studies of the Mayak workers’ radiation exposures and subsequent health effects.
