Six young female dairy animals between the ages of 398 and 479 days were given90 Sr orally for 5 days in the amount of 44 μCi per day per kilogram of body weight. Four of these animals died from 93 to 132 days after treatment; and two are survivors at 3 years after treatment. An average of 41.8% of the90 Sr dose was retained at 11 days after initiation of treatment, and an average of 8% was estimated as retained in the skeletons of the four animals at the time of death. Death was attributed to radiation, since the typical radiation syndrome was exhibited. An average of less than 1% was estimated to be in the skeletons of the two survivors as determined from bone biopsies at 321 days after initiation of treatment.
