Abstract: A real-time atmospheric dispersion and dose assessment system (FADAS) has been developed. It has been used as a basic tool to monitor the atmospheric dispersion of released radioactive materials and radiological dose assessment to the national emergency preparedness system, CARE, since 1995. Tracer experiments have been conducted for the purpose of validating FADAS and analysing the environmental characteristics using automatic sequential samplers. The measured concentration distributions were compared with those simulated by FADAS. Both concentration distribution patterns agreed well.

Keywords: environmental characteristics; large-scale field tracer experiment; national emergency preparedness; radiological dose; real-time atmospheric dispersion model.
