Although termination of recovery process is briefly discussed in section 4.4, the radiological situation remains classified as the existing exposure situation even after the termination according to the 2007 Recommendations. However, the classification labels the areas with a stigma as contaminated, anomalous, inferior and so on. Such stigma could cause prejudice and discrimination both to the residences and area just the atomic bomb survivors have experienced by derogatory term hibakusha. As time goes by, both dose rates and contamination of environment become well reduced and further reduction become unfeasible. In such situation, it is irrational to continue focusing on the small residual doses as the existing exposure, since any protective action about it is impractical. As such residual doses are virtually uncontrollable, it is reasonable regarding it as a part of new natural background radiation dose. I also expect to deepen the discussion on the termination of recovery process in the report.
