ABSTRACT

Active personal dosimeters (APDs) are used by occupationally exposed workers to measure the dose equivalent of radiation that they were exposed to. These dosimeters need to be calibrated to ensure that the dosimeters are accurate. There are two methods for which the APD can be calibrated: the accumulative method and the staggered method. However, there is no recommendation on which of the two calibration methods is most suitable for use. This study aimed to investigate the dependence of the response of APD with various detectors on the two calibration methods. In this work, APDs were irradiated to different dose values of 0.5, 0.1, and 1.5 mSv using accumulative method and staggered method at the Secondary Standard Dosimetry Laboratory – Radiation Protection Services Section (SSDL-RPSS) of the Department of Science and Technology – Philippine Nuclear Research Institute (DOST-PNRI). The results showed that APDs have better response in the staggered method compared to accumulative method and best reflects the practical conditions in the use of the APDs in the field. The results of the study could, therefore, be a basis in developing a more standardized protocol and procedure for the calibration of APDs.
