Risk assessment of accidents involving environmental high-toxicity substances.

摘要: The introduction of new safety legislation in Russia has been accompanied by R&D into risk assessment, especially needed when dealing with high-toxicity substances. In the present article, two models for evaluation dose absorbed recipients as a result instantaneous releases and short-term continuous emissions toxicant to atmosphere are developed. have form definite integrals Green's function. numerical problem obtained is reduced calculation single integrals. It shown that under similar initial conditions, discharge greater than resulting emission toxicant. An interval approach developed estimate sensitivity results errors empirical parameters variables included models. On base introduced definitions variables, vectors functions, estimates there exists an optimal number terms equations inexact parameters. Numerical examples analysis given.
