    "concept_summary": "A patented biotechnological method uses an aqueous suspension of Thiobacillus bacteria together with a feedstock of radioactive ore or waste and a set of variable-valence metals (e.g., iron). The bacteria create a high redox potential (400-800 mV) that allegedly accelerates nuclear decay pathways, converting the feedstock into a range of valuable elements (polonium, gold, uranium, etc.) and their isotopes. The process is claimed to run in closed vessels for two-to-three weeks, yielding industrial-scale quantities.",
