-40- certain coastal areas of the Atlantic Ocean and Gulf of Mexico can be used as receiving waters disposal of packaged, low level, for the controlled radioactive wastes under certain prescribed conditions. One of the areas where radioactivity is being added continuously is the Irish Sea which receives low level liquid wastes from the British Atomic Energy Authority plant at Windscale. Previous to the disposal of these liquid wastes by means of a pipe line to the shallow waters approximately one mile off the British coast, detail. of The circulation of surface waters in the vicinity the outflow persal the problem had been studied in method; was determined by a the breeding and fluorescein dye dismigratory habits of fish which were of commercial interest were studied for the purpose of estimating the uptake of radioisotopes; the uptake of radioiodie by seaweed, which is used in a porridge by local residents, was estimated; and the levels of radio- activity to which the people using the beaches would be exposed were calculated. When all of these factors were taken into consideration the discharge of 1,000 curies per month was authorized. As a result of monitoring studies
