Abstract
In September 1957, a chemical explosion occurred in one of the Mayak facility's nuclear waste storage tank, spreading 740 PBq of radiation over a 23,000-km{sup 2} area. To determine a present contamination of the territory of Kamensk region of Sverdlovsk Oblast, soil samples at 315 locations were collected and analyzed in the course of the field campaign of 1993 and 1994. It was found that a distribution of Sr-90 activity in soil samples is a distribution with 'heavy tail'. Analysis of a histogram representing its frequency distribution and plotting this histogram on doubly logarithmic axes allows to conjecture that this distribution follows the power low. Testing of the power-low hypothesis provided objective evidence that the power-low is a reasonable description of the data. In this case a conclusion follows that radioactive contamination levels of the territory are not well characterized by their averages. (author)
