Measurements of transuranium nuclides in the environment at the Institute for Radiation Protection of the Gesellschaft fur Strahlen- und Umweltforschung mbH, Munich.

Work on environmental transuranium nuclides at the Institute for Radiation Protection of the Gesellschaft für Strahlen- und Umweltforschung mbH, Munich, is briefly described and standard needs are discussed. Fallout plutonium measurements in air dust and precipitation samples started in 1970/1971. The procedure is outlined and results are presented as annual mean and sum values, respectively. Since 1973, transuranium nuclides in primary coolant, stack effluent air and waste-water samples from nuclear power stations are measured. Nuclides detected are 239/240Pu, 238Pu and/or 241Am, 242Cm and 244Cm. Examples of alpha particle spectra are given. Needs for standards in environmental transuranium analysis are discussed
