Abstract: This paper presents results of polymethylmethacrylate (PMMA) dosimeters calibrations that are used as routine dosimeters in CDTN Gamma Irradiation Laboratory. The study was carried out within the framework of the Facility Quality Assurance Program with the purpose of determining the accuracy of the dosimeters used. The dosimeter irradiations were made in a Gamma Irradiator at Nuclear Technology Development Center (CDTN), an R&D Institute connected to the National Nuclear Energy Commission (CNEN), Brazil. The value for estimate of the expanded uncertainty achieved is typical of a routine dosimetry system.

Keywords: uncertainty; PMMA dosimeters; polymethylmethacrylate; gamma processing; absorbed dose to water; dosimeter calibration; dosimetry; gamma irradiation; nuclear energy; nuclear power; Brazil.
