METHOD FOR PRODUCING GROWN RADIOACTIVE DIAMONDS AND GROWN RADIOACTIVE DIAMOND Russian patent published in 2018 - IPC B01J3/06 C30B29/04 C01B32/26 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to the production of synthetic diamonds including an isotope ¹⁴C, possessing β-radiation. Diamonds are iron carbide grown formed directly in the growth chamber from barium carbonate, which is a product of processing spent nuclear fuel and containing in its composition 50–70 % of the isotope ¹⁴C of the total mass of carbon, and not less than 5-fold relative to the total mass of barium carbonate of excess iron.

EFFECT: simplified technology for obtaining radioactive diamonds possessing β-radiation, and also the safety of the synthesis process is increased with the possible use of large amounts of the isotope ¹⁴C.
