5. Inverse Atmospheric Dispersion Modeling in Complex Geometries
University essay from Umeå universitet/Institutionen för fysikAbstract : In the event of a radioactive release in an urban environment the consequent response mustbe swift and precise. As soon as first responders have correct information, they can make anaccurate risk assessment. However, if the position, release rate and time of the radioactiverelease is unknown it is hard to know how the pollutant will spread. READ MORE
