Abstract:
1. A storage product for storing radioactive isotopes, the storage product including: (a) at least one radioactive isotope; (b) a metal alloy including a chemically active metal fraction in an amount effective for chemically reducing organic feed materials, tungsten in an amount effective for producing a close-packed crystalline structure throughout the metal alloy upon solidification of the metal alloy from a molten state, and for each type of expected radioactive emission associated with a radioactive isotope in the storage product, at least one corresponding radiation absorbing metal, each corresponding radiation absorbing metal being capable of absorbing the respective type of expected radioactive emission; and (c) wherein the metal alloy is solidified from the molten state to form a storage ingot with each radioactive isotope, the tungsten, the chemically active metal fraction, and each radiation absorbing metal being substantially evenly distributed within the ingot.
