摘要
Abstract
During the accident of the Fukushima Daiichi Nuclear Power Plant in Japan, a large amount of radioactive substance was released into the atmosphere. In order to more precisely evaluate the released quantity, the Lagrangian puff mode was used to deduce the released quantity of 137Cs with the plot of ground deposition concentration of 137 Cs announced by USA and the continuous meteorological data monitored near the3 Fukushima Daiichi Nuclear Power Plant. The radiological equivalence to 131I released to the atmosphere is estimated at 1. 07×1018 Bq approximately, which is close to the value published by Japanese government.关键词
