Abstract
Within 12 hrs. after intravenous injection of inorganic Co60 into the dog, blood cells contain an insignificant amount of Co60. About 72-75% of the whole blood Co60is precipitable with cadmium hydroxide and remains "non-diffusible" on dialysis. Co60, as Co60SO4, is both readily absorbed from the intestine and "secreted" or "continuously diffused" into the intestinal tract through its wall in the dog. High concentrations of Co60 are found in the liver, intestinal tract, kidney, gall bladder bile and in the bladder urine. The spleen contains a low amount of Co60.
