Working aids for the quick assessment of radiation doses due to accidental radioactive release from nuclear power plants

The initialization of acute emergency measures after an accident in nuclear facilities depends on dose criteria. Therefore a quick dose assessment is necessary, which under unfavourable conditions must be done by the emergency staff without help from a health physics specialist. For this task working aids on a nomographic basis are presented. They start from the assumption that there are measurements of the release of noble gases, iodine and aerosols passing through the stack. Neutral atmospheric conditions, which are the most frequent at the nuclear power plant under view, are assumed. The assessment of the dose on the propagation axis with various wind speeds is very simple. The graphs are included in a collection of work sheets. (orig.)
