To determine the effect of age on the natural radium content of chickens, the radium content was determined from the hatching to adulthood. The chickens werc raised in cages and were fed with pressed feeds containing all necessary nutrients and vitamins. The animals were dismembered, incinerated at 600 deg C, and the ashes were dissolved. The radium conient and the calcium content were determined. The average radium content of the food was 13.5 x 10/ sup -15/ g Ra/g food and the average calcium conteni was 0.014 g Ca/g food. The results showed that up to the moulting period ihe radium content of hens and roosters was the same. After the moulting, which produces a strong disturbance of the normal mineral metabolism, the rooster maintains a single equilibrium value. It was also found that the percentage retention of calcium is from 4 to 20 times that of radium according to the age of the animal. (J.S.R.)
