Calibration of a tertiary standard in N-ISO qualities for radioprotection and personal dosimetry

Dosimetric calibration of radiation monitors and personal dosimeters in different radiological quantities are performed in order to obtain accurate measurements, for this reason the SSDL calculates the dosimetry calibration factor and its associated uncertainty, for each range of use. The calibration factor is performed using the known radiation field method and its uncertainty is calculated according to the ISO recommendations. The SSDL calculates the expanded uncertainty (U_c) with a coverage factor that provides a level of not less than 95 % of confidence. (authors).
