COMPARISON OF EFFECTIVENESS OF 3 RADON DETECTORS (LR115, CR-39 AND SILICON DIODE PIN) PLACED IN A CYLINDRICAL DEVICE THEORY AND EXPERIMENTAL-TECHNIQUES

Researchers at the Laboratory of Nuclear Microanalysis in Besancon (FR ANCE) are developing and improving radon measurements in order to dete ct and analyse, more precisely radon emanation anomalies in both field s of Earth Sciences and Radioprotection. In order to characterize rado n emanation, two complementary techniques are developed: continuous me asurement through a portable proportional counter and passive measurem ents by nuclear track detectors for both fieldwork and laboratory anal ysis. A matematical model is being devised to interpret the nuclear tr ack detector response. This model is performed according to the device characteristics: type of detectors. shape and size of cells and wheth er a membrane is used or not. In addition to the theoritical study, ex perimental radon concentration measurements will be reported.
