Study on ARCL estimation method for radioactivity-contaminated soil

摘要

The aim of present work is to discuss the estimation method of allowable residual contamination levels (ARCL) in radioactivity-contaminated soil near by the nuclear facilities under decommissioning or to be decommissioned. The estimation method would help recommend the regulatory limit on remedial actions for a given site. The methodology of estimating ARCL, the related models, and the parameters used for estimation of maximum annual dose are described. As a estimation example, a contaminated factory site is considered. The maximum in individual doses and ARCL values resulting from various radionuclides are estimated. It must be pointed out that the determination of ARCL is also based on the acceptable dose limit. Thus the cost-effectiveness analysis is necessary in determining the actual acceptable dose limit.
