ABSTRACT
This paper presents results of PMMA (polymethylmethacrylate) dosimeters calibrations that are used as routine dosimeters in CDTN (Nuclear Technology Development Center) Gamma Irradiation Laboratory. The study was carried out within the framework of the Facility Quality Assurance Program with the purpose of to determine the calibration curve and accuracy of the Harwell Amber Perspex 3042 W dosimeters. The irradiations of the dosimeters were made in operational conditions of a Gamma Irradiator at CDTN, an R & D (research and development) institute connected to the CNEN (National Nuclear Energy Commission) (Brazil). The values for estimate of the expanded uncertainties achieved are typical of a routine dosimetry system.
