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.  2. The storage product of claim 1 including a radiation absorbing encapsulant encapsulating the ingot, the encapsulant material including at least one radiation absorbing material for each type of expected radioactive emission within the ingot and further including tungsten in an amount effective for producing a close-packed crystalline structure in the encapsulant. 3. The storage product of claim 1 including no less than approximately one atom of tungsten for every twenty-seven atoms of other elements in the storage product. 4. The storage product of claim 1 wherein each chemically active metal in the chemically active metal fraction is selected from the group consisting of magnesium, aluminum, lithium, zinc, calcium, and copper. 5. The storage product of claim 1 wherein the cumulative total amount of die chemically active metal fraction is no less than approximately forty percent by weight of the total metal alloy. 6. A storage product for storing a fast neutron emitting isotope, the storage product including:(a) a metal alloy including a chemically active metal fraction in an amount effective for chemically reducing organic feed materials, the metal alloy also encompassing a quantity of a fast neutron emitting isotope; (b) a transmutation target fraction forming part of the metal alloy, the transmutation target fraction made up of a transmutation target material for absorbing fast neutrons emitted by the fast neutron emitting isotope; (c) a transmutation emission absorbing fraction forming part of the metal alloy, the transmutation emission absorbing fraction made up of a transmutation emission absorbing material for absorbing emissions resulting from the absorption of a respective fast neutron by the transmutation target material; and (d) tungsten in an amount effective for producing a close-packed crystalline structure upon solidification of the metal alloy; and (e) wherein the metal alloy is solidified from a molten state to form a storage ingot with the fast neutron emitting isotope, the chemically active metal fraction, the transmutation target fraction, and the transmutation emission absorbing fraction being substantially evenly distributed within the ingot.  7. The storage product of claim 6 including no less than approximately one atom of tungsten for every 27 atoms of other elements in the storage product. 8. A storage product for storing radioactive isotopes including:(a) at least one radioactive isotope tungsten in an amount effective for producing a close-packed crystalline structure throughout the storage product upon solidification of the storage product from a molten state, and for each type of expected radioactive emission in the storage product, no less than approximately seven hundred and twenty-seven (727) atoms of a corresponding radiation absorbing metal, each corresponding radiation absorbing metal capable of absorbing the respective type of expected radioactive emission in the storage product; (b) a chemically active metal fraction in an amount effective for chemically reducing organic feed material; and (c) wherein the storage product is solidified from the molten slate 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.  9. The storage product of claim 8 including no less than approximately one atom of tungsten for every 27 atoms of other elements in the storage product.
