Objectives: The course will provide delegates with an understanding of the methods used for the establishment the ionizing radiation reference field and calibration of radiation protection instruments and tools (ionization chambers, survey meters, contamination monitors and personnel dosimeters) and will provide guidance on how to report on calibration measurements. The candidates will learn, using the technical ISO standards and IAEA methods to be implemented practically in their laboratories, how to perform calibration measurements, calculate calibration coefficients and/or calibration factors.
