Study of the kinetics of strontium elimination in the rat
- 1. Commissariat a l'Energie Atomique, Saclay (France). Centre d'Etudes Nucleaires
Description
A kinetic study of strontium elimination was made on rats after a single oral administration of 3 to 5 μcuries of carrier free Sr90. The curve showing the body burden in function of time may be considered as the sum of three exponential terms with half-lives of 14 hours, 72 days, 153 days. The term with a half-live of 153 days represents the metabolism of strontium in the bone; it is predominant since the 17. day and its extrapolation to time zero shows that things seem to proceed as if 18 per cent of the administered amount were deposited in the skeleton.

La cinetique de l'elimination du strontium chez le rat a ete etudiee apres une administration orale unique de 3 a 5 μcuries de 90Sr repute sans entraineur. La courbe representant la quantite presente dans l'organisme en fonction du temps peut etre assimilee a la somme de trois termes exponentiels de periode 14 heures, 72 jours, 153 jours. Le terme de periode 153 jours represente le metabolisme osseux du strontium, il est preponderant des le 17. jour et son extrapolation au temps zero nous montre qu'en definitive, tout se passe comme si 18 pour cent de la quantite administree etaient deposes dans le squelette.
