RADIATION CONTAMINATION OF THE KLYON GOLD - SILVER DEPOSIT

Abstract

As a part of engineering and environmental survey for the development of the Klyon gold-silver deposit (Bilibinsky district of Chukotka Autonomous Okrug), radiation contamination of its territory is investigated. It is established that the level of radioactivity of the ground and soil samples satisfies the radiation safety standards. The results of laboratory analysis of water samples from the Alice brook show that the specific total alpha and beta radioactivity is significantly lower than the corresponding limits. Field measurements of equivalent doses of external gamma radiation have shown that the gamma-background of the territory is within the allowable limit. The absence of the radon danger is shown by indirect features. The results of the study allow one to conclude that the level of the radiation contamination of the industrial site of the Klyon deposit is negligible.
