For example, if one owns a share in a gold mine where the costs of production are US$300 per troy ounce ($9.6 per gram) and the price of gold is $600 per troy ounce ($19/g), the mine's profit margin will be $300. A 10% increase in the gold price to $660 per troy ounce ($21/g) will push that margin up to $360, which represents a 20% increase in ...

Gold-198 (198 Au) is a radioactive isotope of gold. It undergoes beta decay to stable 198 Hg with a half-life of 2.69464 days. The decay properties of 198 Au have led to widespread interest in its potential use in radiotherapy for cancer treatments .
