随着核能事业的蓬勃兴起,核环境问题日益引起人们的广泛兴趣和密切关注。为了对特定地区大气环境现状或潜在污染形势进行剂量学的评价,目前普遍采用高斯烟柱模式预报大气稀释扩散特性。而高斯烟柱模式之应用,关键在确定扩散参数σ。烟羽照相法就是一种定量地确定扩散参数的传统示踪实验方法。鉴于此法具有设备简单,操作方
With the flourishing rise of nuclear energy business, the nuclear environment issue has aroused widespread interest and close attention. In order to evaluate the atmospheric status quo or potential pollution situation in a particular area, dosimetry is generally used to predict the dilution and diffusion characteristics of the atmosphere by Gaussian smoke column. The application of Gaussian smoke pattern, the key in determining the diffusion parameter σ. Tobacco plume photography is a traditional tracer experiment method that quantitatively determines the diffusion parameters. In view of this method has a simple device, the operator
