The objective of this training is to establish the calibration laboratories in ionizing radiation field by providing technical knowledge based on ISO 8529 and ISO 8769 in the field of neutron measurements and surface contamination monitors respectively. It will also provide delegates with an understanding of the technical methods used for the calibration of radiation protection instruments and tools (survey meters, and personnel dosimeters) and will provide guidance on how to report on calibration measurements. The candidates will learn, using tutorials adapted to practical sessions, how to perform calibration measurements, calculate calibration coefficients and/or calibration factors and also how to assess the uncertainty budget.
