【Abstract】 In this paper the uncertainties of the source intensity of chemical harzadous sudden acci dents on environmental risk assessment have been discussed.For the accident assessment probability density function can be used to solve the uncertainties of estimation of the source intensities.For e mergency measure management the uncertainties of accidents source intensity can be obtained by fuzzy sets method.Two examples about liquid chlorine leakage model and propane BLAVE/fireball model were presented.更多还原
