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 (Estonia). A gamma-ray source 137Cs was located during approx. 28 days in one of the village dwelling houses. On the basis of preliminary results, some important details of the history of the accident have been clarified. It was shown, that the gamma-ray source most of the time was placed in the kitchen table drawer. Thus, the absorbed dose rate of whole-body exposure for three inhabitants of the house in Kiisa was defined by this location of the source.
