Results of type testing of MTS-N dosimeters with IEC 62387:2012 standard at the laboratory of external dosimetry in Nicaragua

This study presents the results of the performance of the Laboratory of External Dosimetry (LDE) located at the Laboratory of Radiation Physics and Metrology (LAF-RAM), according to the ISO/IEC 62387:2012. The LAF-RAM is the only External Dosimetry service provider in Nicaragua. The test is considered a validation of the method for the LDE and the Quality Management System of LAF-RAM. The chosen performance testing according to IEC 62387:2012 are Coefficient of variation, Non linearity, Radiation energy and angle of incidence, Dosimeter drop, Light exposure (reader), Over response of radiation incidence and dose build-up, fading, self-irradiation and natural radiation response.The results in general show that all tests are in compliance with the requirements except for some temporal conditions in dose build-up, fading, self-irradiation test.
