ABSTRACT:
A method of decontaminating a site of metals, particularly radioactive metals, is provided. The contaminated material is contacted with pulverized bone, which sorbs the metals from the contaminated material. The bone may be derived from any animals having bone, such as cattle. Prior to use, the organic compounds of the bone are removed, so that inorganic bone composed primarily of hydroxylapatite is obtained. The morphology of the bone, including its crystalline structure and porosity, is maintained. As an alternative to bone derived from animals, synthetic inorganic bone composed of hydroxylapatite and having a physical structure equivalent to animal-derived bone may be used.
