Abstract:
A number of about 130 solid state nuclear track detectors (SSNTD) of CR39 type were exposed in controlled conditions in a Radon Exposure Calibration chamber. The purpose of the work was to study the dependence of the response of the detector to the exposure conditions. Identically shaped CR39 detectors were placed in open cylindrical cups of various geometries (height and radius). For each geometry the side surface of the detector cup was coated with three materials, paper, plastic and aluminium. The effect of the coating of the detector cup on the plate-out of the radon decay products, as well as on the detector response was investigated for each geometry of the detector cup. The dependence of the response on the geometry of the cup was also studied.
