Accumulation of Fallout Caesium-137 in Newborn Infants

Abstract

Wilson and Spiers1 reported that fallout 137Cs in powdered milk accumulated in the body of infants whose body burden could be fitted by an exponential model of a single compartment. Our calculations based on the model of Wilson and Spiers have shown that the concentration of 137Cs in the infant, expressed as pCi/kg of body weight, increases from birth to a maximum at about 50 days and then decreases slowly until the infant is 180 days old, when the observations ceased. The maximum concentration in infants is more than twice that in the mother.
