Development of radiological dose assessment systems to support a radiological emergency preparedness in Korea

This paper describes radiological dose assessment systems which have been developed to support a decision making process against a nuclear emergency. Local scale system FADAS has been used in a national radiological emergency preparedness system. For a validation of FADAS, field tracer experiments were conducted over nuclear sites. Long range model named LADAS has been developed to estimate the effects of radiological emergencies in neighboring countries. METRO-K has been developed for a simulation of the radiological effects due to radioactive materials which have been deposited on various surfaces of an urban area. These systems are useful to provide the radiological information which is essential to choose the suitable countermeasures in case of a nuclear emergency. (C) 2011 Elsevier Ltd. All rights reserved.
