Medical radioisotope

In 1936, a leukemia patient was treated using a radioactive isotope of sodium injected intravenously by Dr. Joseph G. Hamilton, a leader in atomic medicine at the University of California. He was working with Dr. Robert Stone, University of California Professor of Radiology. When he died (18 Feb 1957) the New York Times obituary stated that Hamilton was "believed to be the first ever to inject a radioisotope intravenously in a human being."«*
