Series Description: This report describes a physiological-ecological study of the balance of cesium-137, stable cesium, and potassium in bluegill fish in White Oak Lake. These substances were compared because of their similar physiological properties. The study, conducted between June 1967 and January 1969, focused on the intake, body burden, and excretion of cesium and potassium by bluegill. It discusses the biological half-life of cesium-137 in the fish and notes that cesium-137, stable cesium, and potassium are distributed throughout the fishes' tissue. Amounts of the elements are reported in parts/million.

Data Elements: 89, 103
