日本福岛核电站事故泄漏放射性核素漂移扩散状况分析

Simulation of Radionuclide Dispersion of Fukushima Daiichi Nuclear Power Plant Accident

摘要: 利用自主研发的放射性核素大气扩散模拟计算软件RADCES模拟计算了日本福岛第一核电站事故泄漏放射性核素的漂移扩散情况，给出了放射性核素云团的漂移扩散路径及到达CTBT国际监测系统部分核素监测台站的时间。结果表明，理论预测放射性核素云团到达时间与台站监测到异常样品的时间基本一致。

Abstract: The atmospheric dispersion of radionuclide released from Japan Fukushima Daiichi Nuclear Power Plant was simulated and researched by using the software RADCES which was developed. The route and time of radionuclide drifting and diffusing to CTBT radionuclide stations were calculated. The results are well consistent with the facts.
