摘要

本研究提出一个核子武器爆炸后放射性烟云扩散的模型。选择了一种基于修正沉降模型的模型来模拟核爆炸产生的放射性污染物在大气中的扩散。给出了不同地面爆炸当量和典型气象条件下顺风方向不同距离放射性沉降物的到达时间和剂量率。因此,在已知核爆炸当量和当地气象参数的条件下,可以实现对核爆炸放射性污染物扩散的预测。这为爆炸后受灾环境的估计和救援力量的投入提供了理论依据。

Prediction and Analysis of Nuclear Explosion Radioactive Pollutant Diffusion Model
This study presents a model for the dispersion of radioactive smoke clouds from a nuclear weapon explosion. A model based on a modified Settlement model is chosen to simulate the dispersion of radioactive contaminants from a nuclear explosion in the atmosphere. The arrival time and dose rate of radioactive fallout at various distances in the downwind direction are given for different equivalents of the surface explosion and typical meteorological conditions. Thus, the prediction of the dispersion of radioactive contaminants from a nuclear explosion can be achieved under the conditions of known nuclear explosion equivalence and local meteorological parameters. This provides a theoretical basis for the estimation of the affected environment and the input of rescue forces after the explosion.
