Following a single subcutaneous injection of ^<95>Zr-^<95>Nb to young and adult rats, the concentrations of the nuclides in several organs were studied during the observation period of 63 days. The concentrations in the tibia, lungs, liver, kidneys and spleen of the young rats were much higher than those in the adult rats. The concentration in the tibia, among these organs was the highest both in the youngs and in the adults. Moreover, in the tibia, ^<95>Zr-^<95>Nb retained longer than in other organs. So, if ^<95>Zr-^<95>Nb invade into the body fluid through any route of entry, the radioactive nuclides deposit mainly in the bone and may have possibility to cause radiation injury to the bone marrow.
