Abstract
The retention of47Ca and241Am by 14 parts of the skeleton of growing and mature female rats 7 days after injection has been measured. The various parts of the skeleton possessed widely differing abilities to concentrate both these elements. The bones of the younger rats had a significantly greater ability to concentrate241Am but not47Ca. The implications of these results for the radiation dosimetry of internal contamination by241Am are discussed.
Résumé
La rétention du47Ca et du241Am au niveau de 14 régions du squelette de rats adultes et en croissance a été déterminée 7 jours après injection. Ces diverses régions présentent des activités variables en ces éléments. Les os de rats jeunes présentent des concentrations significativement plus élevées en241Am, mais non en47Ca. Les conséquences de ces résultats sur la dosimétrie de contamination interne par241Am sont envisagées.
Zusammenfassung
7 Tage nach Injektion wurde die47Ca- und die241Am-Retention in 14 Regionenen des Skelets von weiblichen, im Wachstum begriffenen sowie ausgewachsenen Ratten gemessen. Die verschiedenen Skeletteile zeigten sehr unterschiedliche Fähigkeiten, diese beiden Elemente anzureichern.241Am wurde in den Knochen der jüngeren Ratten signifikant besser angereichert als47Ca. Die aus diesen Resultaten zu ziehenden Folgerungen werden im Hinblick auf die Strahlungsdosimetrie bei interner Kontamination durch241Am erörtert.
