Natural Radionuclides Concentration and Enrichment Factors in Burned-Coal Domestic Bottom Ash in Ili Valley of Xinjiang
摘要
Abstract
Due to measuring the background value of specific activity of radionuclides (238 U, 232 Th,226 Ra,40 K),48 collected samples of bottom ash of coal in the coalfields were analyzed by Gamma-ray spectrometer at China Nuclear Radiation Protection Research Institute.The results show that the specific activity are 104.4 Bq/kg (238 U),37.6 Bq/kg (232 Th),126.7 Bq/kg (226 Ra)and 101.7 Bq/kg (40 K).The enrichment factors(EF)of the radionuclides in bottom ash relative to the input coal during the combustion process range from 0.1 to 26.6 for 238 U, from 3.3 to 309.2 for 232 Th,from 0.4 to 284.0 for 226 Ra and from 1.7 to 225.5 for 40 K, whereas the relative enrichment factors(REF)are 0.01 to 19.97 (238U),0.06 to 77.9 (232 Th)and 0.02 to 54.5 (226 Ra).The specific activity of 238 U,226 Ra,232 Th and 40 K present the lowest in bottom ash in Ili Valley of Xinjiang compared with other areas and nations.关键词
