Popis: International audience ; This work explores the applicability of previous finings of other researchers that the radioluminescence of air can be used for detection of alpha sources and 222Rn detection. We propose the triple-to-double coincidence ratio counter (TDCR) as a suitable detector to detect the radioluminescence light produced by the alpha particles in the air. We developed a TDCR-based 222Rn measurement system based on the detection of air alpha- radioluminescence. The system is connected to a 222Rn calibration facility and its response is studied by comparison to a reference 222Rn monitor that utilizes a PIPS detector. The linearity of response of the system is verified with certified 239Pu sources in a large alpha emission rate range. The 222Rn response of the system is benchmarked against the reference PIPS detector under stable and varying 222Rn concentrations. An excellent agreement between the two systems is observed. It appears that the proposed method is feasible and has one very distinct advantage the memory effect due to deposition of 222Rn progeny can be eliminated entirely very easy by changing the vial in the TDCR counter. The proposed method can find application for monitoring of 222Rn concentration during calibration of radon detectors (e.g. solid state nuclear track detectors).
