Low-Level Radon Activity Concentration-A MetroRADON International Intercomparison

Int J Environ Res Public Health. 2022 May 10;19(10):5810. doi: 10.3390/ijerph19105810.

Abstract

An international comparison of continuous monitors measuring radon activity concentration was performed to validate the traceability of the European radon calibration facilities. It was carried out by comparing the secondary standards used by these previous facilities, ranging from 100 Bq·m-3 to 300 Bq·m-3. Secondary standards were individually compared to a secondary reference device previously calibrated in a reference radon atmosphere traceable to a primary standard. The intercomparison was organized by the National Institute for Nuclear, Chemical, and Biological Protection (SUJCHBO) in the period from October 2019 to April 2020 within the European Metrology Program for Innovation and Research (EMPIR), JRP-Contract 16ENV10 MetroRADON. Eight European laboratories participated in this study. The results of the experiment are presented and discussed.

Keywords: calibration; interlaboratory comparison; radon; radon activity concentration; traceability.
