Abstract
The method of human tooth enamel electron spin resonance (ESR) dosimetry was used to obtain individual absorbed doses of residents of settlements in the vicinity of the uranium mine and uranium processing plants in Stepnogorsk city, Akmola oblast, Kazakhstan. Measured teeth samples were extracted according to medical indications. In total, 33 tooth enamel samples were analyzed from the residents of Stepnogorsk city (180 km from Astana city, Kazakhstan). Some results of dose estimation of residents staying in Stepnogorsk city and workers of uranium enterprises were included. About 10 tooth samples have been collected from the workers of uranium plant. Results of tooth enamel dose estimation shows us small influence of working conditions to workers, the maximum excess dose is less then 100 mGy. This is pilot study of ESR dose estimation, for a final conclusion additional sample is required. Some results of excess estimation by ESR dosimetry method from Ust-Kamenogorsk region have been included to this presentation. This region is well known place of uranium processing industry.
