GAMMA-RAY DOSE ASSESSMENT AFTER THE 1994 RADIATION ACCIDENT IN KIISA (ESTONIA) - PRELIMINARY-RESULTS

Dose reconstruction using thermoluminescence (TL) of quartz, extracted from the ceramic plant pots, and using EPR of the sugar samples, was performed after the 1994 radiation accident in the village Kiisa (Esto nia). A gamma-ray source Cs-137 was located during approx. 28 days in one of the village dwelling houses. On the basis of preliminary result s, some important details of the history of the accident have been cla rified. It was shown, that the gamma-ray source most of the time was p laced in the kitchen table drawer. Thus, the absorbed dose rate of who le-body exposure for three inhabitants of the house in Kiisa was defin ed by this location of the source. Copyright (C) 1996 Elsevier Science Ltd
