Workshop on Reliability of Atmospheric Dispersion Models

NRPB, 22-23 October 2001

The ADMLC organised a meeting on the reliability of atmospheric dispersion models with particular emphasis on the aspects related to the licensing process for nuclear installations in the UK. The meeting was intended to address two questions:

what do regulators want from atmospheric dispersion models?
how reliable are models for those needs?

The following papers were presented.
