摘要：

Indoor radon concentration represents an important public health challenge, for simple and inexpensive measurement devices and methods, suitable for large-scale indoors radon measurements, are required. Nuclear Track Methodology, by using a closed-end cup device as a radon chamber is an attractive option for such large-scale indoor radon measurements. A comparative analysis of the detection efficiency of four different (one commercial and 3 specially designed) passive closed-end cup devices for the measurement of indoor radon concentrations is presented. CR-39 (Lantrack (R)) polycarbonate was the detector material. The four devices were simultaneously exposed to a mean radon concentration of 860 +/- 60 Bq m(-3) inside a closed room for periods of one, two and three months. An AlphaGUARD (R) radon monitoring system was used to continuously monitor the radon concentration within the room. The chemical etching and reading procedures were carried out following a well-established protocol for indoor radon surveys. The detection efficiency and the exposure-time-response relationship of each of the devices were determined. (c) 2012 Elsevier Ltd. All rights reserved.
