Modern society is confronted with emerging threats from chemical, biological, and
radiological (CBR) hazardous substances, which are intensively utilized in the chemical …

In case of a nuclear accident, the source term is typically not known but extremely important
for the assessment of the consequences to the affected population. Therefore the …

Numerous uncertainty factors in dispersion models should be taken into account in order to
improve the reliability of predictions. The ability of a mesoscale meteorological model to …

This paper presents an efficient algorithm for estimating the unknown emission rate of
radionuclides in the atmosphere following a nuclear accident. The algorithm is based on …

The problem of correcting the pollutant source emission rate and the wind velocity field
inputs in a puff atmospheric dispersion model by data assimilation of concentration …

Radiation from the deposited radionuclides is indispensable information for environmental
impact assessment of nuclear power plants and emergency management during nuclear …

The main purpose of this study is to propose a decision support system that deals with the
uncertainties in a model of atmospheric dispersion and in meteorological data (speed and …
