Performance evaluation of radon monitors at IFIN-HH, Romania.

Starting in 2022, the calibration of various radon monitors received from customers was performed for the first time in Romania by LMRI at IFIN-HH, designated by CNCAN as a calibration laboratory. The purpose of the study was to analyze the radon monitors responses and their uncertainties, and finally compare their performance with the standard radon monitor AlphaGuard in order to improve the calibration process in the future. Measurement results and the uncertainty budgets are presented in the paper.
