摘要
The elemental composition of colcothar obtained from 10 samples of raw material taken from a cave in paleozoic rock on the northern slopes of the Turkestan mountain range was investigated. The samples were obtained by repeatedly extracting the initial material using water followed by evaporation. It was observed that in the γspectrum of colcothar, the total absorption peaks for γradiation from 226Ra ( 238U series), 226AC ( 232Th series), and their daughter radionuclides were comparable in intensity with the background spectrum. It was also observed that the 1462 KeV γradiation from 40K was more than 4 times higher than the background value.
