Metal alloy and metal alloy storage product for storing radioactive materials

A liquid metal alloy bath for producing a storage product for storing one or more radioactive isotopes, the liquid metal alloy bath comprising:

• (a) a chemically active metal fraction;
• and
• (b) for each type of expected radioactive emission associated with a radioactive isotope to be stored 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,
• (c) wherein each corresponding radiation absorbing metal in the metal alloy is substantially evenly distributed throughout the volume of the liquid metal alloy bath.

A storage product for storing radioactive isotopes, the storage product comprising:

• (a) at least one radioactive isotope;
• and
• (b) a metal alloy including a chemically active metal fraction in an amount effective for chemically reducing organic feed materials, a compact crystal forming metal fraction in an amount effective for producing a close packed crystalline structure upon solidification of the metal alloy, 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,
• (c) wherein the metal alloy is solidified to form a storage ingot with each radioactive isotope, the chemically active metal fraction, the compact crystal forming metal fraction, and each radiation absorbing metal being substantially evenly distributed within the ingot.
