Element collecting from hydrogen to bismuth (except the radioactive technetium and promethium) are collected, with the exceptions of the extremely long-lived thorium and uranium. It is possible to source other radioactive elements, such as radium (usually in the form of radium sulphate as part of luminescent paint on antique watch hands), tritium - a radioactive isotope of hydrogen, americium (in the form of radioactive buttons containing 0.29 micrograms of americium extracted from older smoke detectors), and technetium. Element collecting Element collecting is the hobby of collecting the chemical elements. Many element collectors simply enjoy finding peculiar uses of chemical elements. Others enjoy
Board of Radiation and Isotope Technology also manufactures self-luminescent tritium filled sources. The organisation also develops radiation-based medical equipment to treat cancer. BRIT operates three radiation facilities, one of them a spice and allied products irradiation facility in Vashi and another a "Krushak" (Krishi Utpadan Sanrakshan Kendra) radiation processing plant at Nashik. G. Ganesh is BRIT's Chief Executive officer since 1 August 2015, succeeding Anil Kumar Kohli (2006-2015). Board of Radiation and Isotope Technology Board of Radiation and Isotope Technology in short known as "BRIT" is a unit of the Department of Atomic Energy with its headquarters in Navi Mumbai, India. It is involved in production,
