Catalogue of countermeasures to be taken in case of a nuclear accident

One of the experiences made in Germany after the Chernobyl accident in 1986 was that a compilation of countermeasures regarding the time phases of an airborne plume is necessary. To achieve this aim, the Catalogue of Counterm easures ("Survey of measures designed to reduce the radiation exposure afte r events of considerable radiological consequences") was created The purpos e of this Catalogue is to be a primary guide for selecting protection measu res. The Catalogue consists of two parts. The first part allows time-phase related decisions on initiating disaster control and precautionary counterm easures in the agricultural and in the non-agricultural area. The second pa rt of the Catalogue contains supplementary information, for example a summa ry on theoretical principles together with the most important equations on which the Catalogue is based.
