Abstrakt: THERE have been many investigations of the metabolic behaviour of caesium-137 in man1,2and experimental animals3. The findings showed that the biological half-times for caesium-137 increased with age4. In view of the scarcity of data on the retention of caesium-137 in young animals, we have investigated the phenomenon in suckling and weanling mice, and found an unusual retention pattern in sucklings, which had a longer biological half-time of 7.5 days.
