Computer Simulation of Gamma Irradiation Energy Deposition in Mosfet Dosimeters

Abstract

developed because a experimentally measure the detailed dosimeter response is hardly [13]. However, in this case The application of the MOSFET as detectors or device assumed charged particle equilibrium, which did not exist components in Power Pulse Technique (PPT) requires in the sensitive volume of the dosimeter. Therefore their investigation of their characteristics in the radiation fields model failed to calculate the actual dose, and the outputs Limitatis iwere regarded as only a first-order approximation at best. Limitations in measurement of MOSFET detectorTeamo u ae sdtriaino h eoie characteristics are successfully overcomed using Monte The aim of our paper is determination of the deposited Carlo program for simulation of the radiation transport energy distribution in MOSFET structure using computer through the detector structure. In this paper the calcusimulation based on Monte Carlo techniques. application possibilities of prestige FOTELP and The calculaon of deposited energy in the sensitive PENELOpE programs for computation of the deposited volume of dosimeters iS of special interest. For this energy and doze distribution in the sensitive volume of purpose advance computer programs FOTELP [16] and MSeTgy wer doze prseted.uti inthesensitivevolumeof PENELOPE [17] were used. Based on the obtained results it could be possible to propose models of
