RADIATION CHARACTERISTICS OF VISEAN ROCKS OF CARBONIFEROUS SUITES IN THE AREA CHAN''VINSKOE DEPOSITS OF LIMESTONE
The article describes the evaluation of potential radiation hazard of the visean rocks of the Suite of carbon fiber. Deposits out in the Eastern part of the quarry Chan'vinskoe limestone Deposit (Perm region). The studied rock samples are characterized by low power ambient dose equivalent rate continuous gamma-radiation, the permissible activity of natural radionuclides K-40, Ra-226, Th-232.
