Nuclear and radiological emergencies

Prevailing weather conditions play an important part in the consequences of an accident or other event resulting in a release of radioactive substances to the atmosphere. Airborne releases are transported by the wind, spread and diluted by turbulent atmospheric processes and deposited onto the ground by dry and wet scavenging. Rain increases deposition and consequently also dose rates at the ground level. Rain data is therefore very important in predicting and evaluating the possible environmental consequences of radioactive releases. In addition, radar data can be used in focusing various measurement activities in the potential areas of interest.
