Radioisotopes exportedIn 1947, radioactive isotopes produced from phosphorus-31, arrived at Canberra, Australia, being the first export of radioisotopes from the U.S. They were to be used in Australia's X-ray and medical laboratory. Oak Ridge National Laboratory in Oak Ridge, Tenn., produced the isotopes as a by-product of the chain reaction in a uranium pile. They travelled by airplane via San Francisco, California. |
