Intercomparison of Indoor Radon Measurements Under Field Conditions In the Framework of MetroRADON European Project

Abstract: Interlaboratory comparisons are a basic part of the regular quality controls of laboratories to warranty the adequate performance of test and measurements. The exercise presented in this article is the comparison of indoor radon gas measurements under field conditions performed with passive detectors and active monitors carried out in the Laboratory of Natural Radiation (LNR). The aim is to provide a direct comparison between different methodologies and to identify physical reasons for possible inconsistencies… Show more

“…The reference radon flux value for each area is obtained by consensus applying the iterative algorithm A, according to ISO 13528:2015 [ 29 ]. This algorithm is described and applied in other international interlaboratory exercises [ 20 , 30 ].…”

“…Still, there is no harmonization between the existing radon flux systems and methods. In addition, there is a lack of interlaboratory exercises to compare such systems and to identify possible inconsistencies between their responses [ 20 ].…”

“…The greater use of the track detector method for measurement of residential radon can be explained by the fact that track detectors are passive devices requiring neither electric current nor a pump to function in the sampling environment, whereas active devices require electricity and enable continuous monitoring and recording of radon gas concentrations and fluctuations across the measurement period [47]. In addition, track detectors are cheaper than other types of detectors, and extremely reliable if used with the appropriate methodology [52] Many of the studies reviewed did not report the geometric mean or median, both of which are important measures, since radon concentrations tend to follow a log-normal distribution. Six studies were excluded after a reading of the full text because they measured radon in fewer than 10 homes.…”

“…Radon detectors were calibrated both by the producer and within the framework of internal laboratory control of the Institute of Industrial Ecology. RadoSys regularly participate in intercomparison of radon measurements with RSKS detectors, in particular, recently, in international comparison of radon/thoron measurement instruments 40 and in the framework of MetroRADON Project 41 . In the Institute of Industrial Ecology, the calibration coefficients provided by producer were verified by exposure of radon detectors in a radon chamber equipped with a radon source and radon-monitor AlphaGUARD PQ2000 PRO as a reference device, which was previously calibrated with using a NIST radon emanation standard.…”
