Title: EPR Tooth Dosimetry of SNTS Area Inhabitants
Published: December 29, 2007
Abstract: Determination of external dose to teeth of inhabitants of settlements near the Semipalatinsk Nuclear Test Site (SNTS) was conducted using the EPR dosimetry technique to assess exposures associated with radioactive fallout from the test site. In this study, tooth doses have been reconstructed for 103 persons with all studied teeth having been formed before the first nuclear test in 1949. Doses above that from natural background, termed accident doses , were found to lie in the range from zero to approximately 2 Gy, with one exception, a dose for one person from Semipalatinsk city of approximately 9 Gy. The variability of reconstructed doses within each of the settlements demonstrated heterogeneity of the deposition as well as variations in lifestyle. The village mean doses for the settlements were in the range from a few tens of mGy to approximately 100 mGy.
