The use of SSNTDS in the retrospective assessment of radon exposure in high radon rural communities in Yugoslavia

A description is given of the field application of a technique using CR-39 and LR 115 detectors to determine alpha recoil implanted Po-210 surface activity on domestic glass artefacts in dwellings. These investigations took place in two small stable rural communities in uraniferous areas of Yugoslavia where between 32% and 74% of contemporary indoor radon levels were found to be above the commonly used Action Level of 200 Bq m(-3) and individual levels as high as 8700 Bq m(-3) were measured. The Po-210 data is used to retrospectively estimate radon exposures in these communities. Comparisons between the retrospectively estimated radon exposures and those being received at present are made.19th International Conference on Nuclear Tracks in Solids (ICNTSs), Aug 31-Sep 05, 1998, Besancon, Franc
