Intercalibration and validation of personal dose monitoring of professional radiation workers at the Semipalatinsk nuclear test site

Personal monitoring of occupational radiation workers at the Semipalatinsk Nuclear Test Site by the Institute of Radiation Safety and Ecology (IRSE), National Nuclear Centre (NNC) Kurchatov, has been validated. Good agreement has been found between Kazakh and German dose evaluations. Doses received by workers included in the validation program were well below internationally accepted occupational regulatory standards. An intercalibration of German and Kazakh dosimeters also yielded good agreement. Quality and methods of occupational dose monitoring at IRSE correspond to international standards. (author)
