[2I11] Evaluation of Short and Long-Term Behavior of Radioactive Nuclides Distributed in Fukushima Daiichi NPP

(2)Major subjects for evaluation of short and long-term radioactive nuclides behavior after severe accident

*Hidetoshi Karasawa1, Shunsuke Uchida1, Chiaki Kino1, macaroni Nato1, Masahiko Ohsaka2 (1. IAE, 2. JAEA)

Keywords:FP distribution, exposure risk, radioactive nuclde, remove debris

Exposure risk was evaluated based on the distribution of FPs obtained by the analysis of 1F using SAMPSON code. But the amout of radionuclides might be changed during a long term after the accident. Major subjects for changing the status of radioactive nuclides were discussed.
