I have found much on radioactive gold - but there are rational explanations for each - for starters:vanderbilt.edu orau.org At some time during the 1930s and 1940s, gold seeds that had previously contained radon-222 were melted down by an unknown individual or individuals. Presumably this occurred somewhere in New York State. The gold, contaminated with the long lived decay products of radon (Pb-210, Bi-210 and Po-210), was mixed with uncontaminated gold and used to manufacture jewelry. But that was because the radon was mixed in with the gold.washingtonpost.com A plant report included in the lawsuit filings may shed light on the degree of contamination in the gold. In a radiological survey of the plant last year, technicians discovered gold flakes inside an old ingot mold used for gold recovery. The fish scale-sized flakes were tested and found to emit radiation at a rate of 500 millirems an hour, the report said. By comparison, the average person receives between 200 and 300 millirems each year from all sources, including X-rays, radon gas and cosmic radiation from space. Yet the ingot probably was still emitting radiation - if that was pure gold and they had taken the radiation tests several months after removing the flakes from the ingot - I believe they would not find such high levels of radiation in the gold flakes as the longest lived isotope is only in months. and another:jnm.snmjournals.org Treating with radioactive colloidal gold - transient effectsbnl.gov The Right Element for the Job Like a carpenter chooses the right tool for his task, the physicians must also choose the right radionuclide for a nuclear medicine procedure that will help find and/or treat his or her patient's cancer. On March 29, BNL researcher Leonard Mausner will present the newest components of the experimental toolkit, made through a team effort in the radionuclide and radiopharmaceutical research program in the BNL Medical and Biology Departments. He will also describe each isotope's individual uses. For example, a short-lived form of radioactive gold can be attached to a cancer-specific antibody, to help locate and treat tumors in the body. And a form of fleetingly radioactive platinum shows promise in treating tiny breakaway cancers throughout the body of a patient being treated for a larger, central cancer. Perhaps in the past if you subscribe to the ancient astronauts theory of history gold/silver had medicinal purposes that was lost to time and history. Nuclear medicine is interesting.
