摘要
Abstract
The radioactive acceptance criteria for solid waste in municipal solid waste landfill (MSWL)were preliminarily established.First,the radioactive acceptance crite-rion of 5×10 -5 lifelong cancel risk was determined as the target value of acceptable risk level.And then combining with the design basis and the regulatory requirement of MSWL in China,the lifecycle health risk evaluation method for MSWL was established. Finally,using the target value of acceptable risk level and health risk evaluation meth-od,the acceptance limit for radionuclides in solid waste in MSWL was derived.The results show that the derivation activity concentration values of short-life radionuclides (T 1/2 <30 a)are more than the clearance levels of respective nuclides in the Chinese standards (e.g,the calculated activity concentration value of 60 Co is 0.61 9 Bq/g,and its clearance level is 0.1 Bq/g),and the derivation activity concentration values of long-life radionuclides (T 1/2 ≥30 a)are same as the clearance levels of respective nuclides in the Chinese standards.关键词
