Biological Half-Life of Cesium-134 in the Red Imported Fire Ant, Solenopsis invicta

Three castes of the red imported fire ant, Solenopsis invicta Buren were fed a radioactive (cesium-134) diet to determine biological half-lifes. Results from gamma spectrophotometric analyses indicated that the biological half-life of cesium-134 in winged reproductives (females), major workers, and minor workers was 82, 74, and 62 hr respectively.
