Abstract

In Romania, the national regulations impose the use of the film dosemeter as principal means for personal radiation protection monitoring. One of the parameters of the incident photon radiation which has an important influence on the dosemeter response is the photon energy. In this paper the conclusions of the studies concerning the dependence of the dosemeter response on the photon energy are presented. For this study, the “personal monitoring” Agfa Gevaert, class B, index 3, films were used together with a FD-III-B badge, since this dosemeter is in current use in Romania. The dose equivalent measuring Chalcogenide Letters Vol. 5, No. 4, April 2008, p. 58 - range is between 0.1 mSv and 1 Sv and the energy range of the photons is between 20 keV and 9 MeV. For studying the influence of the photon energy on the film response, these films were irradiated at the same value of the dose equivalent, Hp(10) = 1 mSv, for several values of the photon energy. The paper also presents the conditions for the film processing and the results concerning the dependence of the optical density on the photon energy. The activities which involve the use of ionizing radiation cover a large area from the biomedical applications to the industrial applications, including nuclear power plants..
