THE PERFORMANCE OF DIFFERENT TYPES OF ETCHED TRACK RADON DOSEMETERS IN TWO INTERNATIONAL INTERCOMPARISONS
Two intercomparisons of etched track radon and radon daughter dosimetry have been held. Thirtyone sets of results are analyzed. Participants used Kodak LR-115, polycarbonate and FADC (CR-39) as detector materials, chemical and electrochemical etching, and manual and automatic track counting. It is shown that all of the materials and techniques used can provide accurate dosimetry of radon. LR-115 and FADC can measure lower levels of radon than polycarbonate, but some supplies of them suffer from high backgrounds. Automatic counting techniques can give results as good as, or better than, manual techniques. Non-linearity of response can be a problem when electrochemical etching is used, but this can be overcome.
