Development of decontamination guidelines for the management of contaminated areas as an emergency prepardness

Decontamination works were carried out on large area in Japan. Lessons learned from the responses to emergencies over the past years were led to similar conclusions. One of the lessons was that impossibility to establish standards consistent with radiological protection principles after an emergency. To reduce radiological and non-radiological (e.g. economic, social, and psychological) risks for emergency situation, it is necessary to pre-establish guidelines for emergency preparedness. Korea government established a risk management standard manual for radiological emergency in 2016. In this study, decontamination guidelines for the management of contaminated areas were developed as an emergency preparedness. The decontamination methods were divided into buildings, soils, roads, and vegetation. Each decontamination method was applied with reference to the decontamination technique data sheet. The results of this study are expected to be used for development of decontamination standards
