核爆炸产物放射性衰变过程的研究

Study on Decay Process of Radioactive Products after Nuclear Explosion

核爆炸后产物放射性和毒性及其随时间的变化是有关安全保障和环境保护的主要问题．利用新开发的数据库和程序对该问题进行了详细的理论研究，给出了裂变产物的放射性活度、生物潜在危害因子和能量沉积等量的演化情况，列出了主要放射性核的贡献。

The evolution of radioactivity and poisonousness of the products after nuclear explosion is very important for safety and environmental protection. The detailed study of the evolution of radioactivity of fission products, biological hazard potential, energy deposition and so on was performed by using the new data base and code. The contributions of the main radioactive nuclei and the evolution of radioisotopes in soil and rock are also discussed.
