[Relation between the levels of mineral components and mechanical properties of the bones in dogs after a single acute whole-body irradiation].

Mineral components and mechanical properties of different compartments of the femur and jaws of 25 dogs, 10 of which were exposed to single total-body acute irradiation at a dose of 4.0 Gy, were investigated. The mineral content and strength of spongy bone of the femur of the irradiated dogs declined. It was demonstrated that the strength limit and mineral density were closely correlated. No changes were seen in cortical bone of the femur after irradiation.
