In order to establish the national radon level according to the ICRP recommendations, radon levels should be estimated in different living environments (dwellings, workplaces, hospitals, etc.). A particular attention should be given to the correctness of the radon concentration measurement devices in order to maintain their traceability to primary standard laboratory. Radon monitor systems have thus been calibrated using a NIST standard source which is considered as an important step in standardizing radon measurement methods.
In this paper, we describe the system used in our laboratory for the verification against radon response of different radon monitors such as Electret Ion Chamber (EIC) and AlphaGUARD continuous radon monitor (AG), and then we present comparison between these two measurements devices used in some locations at the Centre de Recherche Nucléaire d’Alger (CRNA). As results, EIC system produces results comparable to those produces by the AG system.
