Fast Risks Evaluation Method For Chemical Cases

Aiming at imperilment effect of toxic clouds diffusion when chemical disasters occur or terrorists carry out chemical terrors, a fast risks evaluation method, based on integral theory of Monte Carlo method, is developed. The method can simulate toxic clouds diffusion as well as their risk depth, risk dimension, and poison mortality rate. During emergency and succor, we can apply the method to evaluate rapidly potential risks of chemical cases so as to provide decision-makers with scientific advises to reduce loss and panic.
