A method has been developed by which large samples of mineralized bone, containing an alpha-emitter, can be embedded in Spurr's resin in a fraction of the time required by conventional methods. Bone samples were freeze-dried or fixed and dried prior to impregnation with Spurr's resin under vacuum. Sections were cut for the preparation of either alpha-track(More)
Female rats were used to study the loss of plutonium from hepatic and splenic macrophages. The plutonium was administered intravenously either as a "soluble" [Pu] ferric hydroxide colloid or as an "insoluble" plutonium dioxide suspension. The "soluble" plutonium was lost much more rapidly from the liver than the "insoluble" plutonium. If the iron status of(More)
The distribution and retention of intravenously injected hexavalent uranium-233 in the skeleton of the female rat has been investigated using a variety of autoradiographic and radiochemical techniques. These showed that approximately one third of the injected uranium is deposited in the skeleton where it is retained with an initial biological half-time of(More)
The distribution and retention of intravenously injected 241Am in the skeleton of the female rat has been investigated using autoradiographic and radiochemical techniques. The studies were designed to assess the dosimetric and toxicologic implications of an 241Am intake by man. They showed that in the rat approximately one third of the intravenously(More)
A solution containing 226Ra chloride was injected into young female rats via the saphenous vein. Subsequently, the distribution and retention of the 226Ra in the skeleton was studied. The results show that: 226Ra is initially deposited in the rat femur as a volume deposit and is fairly evenly distributed throughout the bone matrix. Much of the 226Ra(More)
