Transfer to milk of ingested radiolead.

Abstract Four lactating cows were confined in metabolism stalls and each given a single oral dose of 203Pb(NO3)2. For the next 5 days, all milk, urine and feces from the four cows were collected and the 203Pb content of each measured. Peak activity appeared in the milk 30 hr following administration of the nuclide and the activity in milk declined with a half time of 70 hr. The transfer to milk was limited, less than 0.02% of the ingested 203Pb was secreted. The limited milk transfer suggests that radiolead which may result from the detonation of nuclear explosives is of little direct significance to man, relative to other radionuclides produced.
