Clearance of orally administered 115mCd from rat tissues

Peak 115Cd levels in the liver, kidneys, spleen and duodenum of the rat, following a single oral dose, fell exponentially. Half-clearance time for 115mCd is highest in the kidney (30 days) followed by the liver (6.8 days), the spleen (5.5 days) and the duodenum (3.5 days).
