As it cannot be excluded that such incidents can happen again, a system of emergency preparedness for the protection of the population is necessary. In order to be able to take appropriate protective measures in the event of an emergency, the contamination (pollution) of the environment has to be forecast, measured and the resulting radiation exposure of the population has to be ascertained.
