[en] The annual quantities and types of radioactive materials released from three operating nuclear electric generating facilities and a nuclear fuels-reprocessing facility are presented and discussed. The period of interest spans the years 1969 to 1972 with some additional data for those facilities operating before 1969. Release quantities have been well controlled, considering the nature and vintage of the operations. Presented are the results of environmental surveillance relying most heavily on the activities of the New York State Department of Environmental Conservation. Observations at Indian Point 1 and at Nuclear Fuel Services, Inc., have led to the discovery of several facility-related radioisotopes in environmental media. These two facilities are of comparatively early vintage, have produced slightly larger amounts of waste materials, and have been the subject of more comprehensive studies than others in the state. Dose consequences to hypothetical persons and to populations within 50 miles of the facilities are addressed. It should be stressed that all individual doses presented are hypothetical. Doses via the drinking-water and cow's-milk pathways are particularly conservative. In each case these hypothetical doses are at least an order of magnitude or more greater than the known worst case. No excessive exposure levels are known to have existed. All operations resulted in postulated exposure levels well within applicable regulations or guidelines generally being a small percentage of these values. Population doses have been surprisingly consistent through the period of interest. They are insignificant in comparison to the dose to the population of the state from natural or medical sources.
