Investigation of the unusual behavior of cesium-137 and other radionuclides in the Florida environment. Progress report, September 1, 1972--September 1, 1975

Levels of fallout 137Co in southeastern Florida milk indicate milk drinkers in the area have ingested 17 mrem in excess of the national average in the period 1963 to 1973. Analysis of feed in dairy rations in the area show a transfer of seven percent of activity from feed to milk. Range cattle had five times the cesium activity as meat from dairy animals. The increased amount of hay in the ration, plus higher activity levels in the unimproved pasture, account for the increase. Eighty percent of the original fallout is still active in the southeastern Florida biosystem
