The aim of this work is to evaluate variants of the calculation of the average multiyear meteorological dilution parameters based on a Gaussian dispersal model for constant emissions. Three variants of the calculation of the meteorological dilution parameters which are distinguished by different degrees of detailing of the atmospheric stability categories and their characteristic wind speeds, which determines the difficulty and complexity of the calculations, are examined. It is shown that at distances >1000 m from the source of emissions all three computational variants give comparable results and can be used to estimate the radioecological conditions in the environment. The computational variant 1, which takes account of the realization of the atmospheric stability category and its corresponding gradations of wind speed, is the preferred option. It makes it possible to obtain more accurate estimates of the constant radioactive fallout density.

不同气象稀释参数计算方法中地球表面放射性核素沉降密度的评价

这项工作的目的是评估基于恒定排放的高斯扩散模型计算平均多年气象稀释参数的变体。对气象稀释参数计算的三种变体进行了检查，这些变体通过大气稳定性类别的不同详细程度及其特征风速来区分，这决定了计算的难度和复杂性。结果表明，在距排放源 1000 m 以上的地方，所有三种计算变量都给出了可比较的结果，并可用于估计环境中的放射生态条件。计算变体 1，考虑了大气稳定性类别的实现及其对应的风速等级，是首选。这使得获得恒定放射性沉降密度的更准确估计成为可能。
