| 中文摘要: |
| 利用修正了的高斯模式探讨核电站核素污染事故中的核素扩散。分析了边界条件、气象条件和核素衰变规律对核素扩散污染的影响，并进一步讨论了核素的污染范围、距源距离及核素沉积量，可作为确定应急安全的理论依据。 |
| 英文摘要: |
| The radioactive elements’ diffusion at the nuclear safety events in a nuclear power station was discussed in this paper using a modified Gauss model. The factors such as boundary conditions, wind velocity and the decay laws of the radioactive elements, which influence the diffusion contamination of the elements, have been analyzed. Further, contaminated zone, the distance from the elements releasing source to the contaminated zone, and the sedimentation of the elements were evaluated. |
