San Francisco Startup Claims Nuclear Transmutation of Mercury into Stable Gold
San Francisco startup Marathon Fusion claims to have converted mercury into stable gold using nuclear transmutation, reportedly surpassing CERN's previous record by a factor of 10. The process involves fusion-generated neutrons transforming mercury-198 into mercury-197, which decays into gold-197. While the company shared some gamma-ray data, it has not disclosed the quantity of gold produced or detailed experimental results, leaving the scale and commercial viability uncertain. The breakthrough also includes producing medical isotopes, but radioactive byproducts remain a challenge.
