Luminous paint paint was used to illuminate Apollo Lunar Module electrical switch tips and painted on control panels of the Lunar Roving Vehicle. The latest generation of the radioluminescent materials is based on tritium, a radioactive isotope of hydrogen with half-life of 12.32 years that emits very low-energy beta radiation. The devices are similar to a fluorescent tube in construction, as they consist of a hermetically sealed (usually borosilicate-glass) tube, coated inside with a phosphor, and filled with tritium. They are known under many names – e.g. gaseous tritium light source (GTLS), traser, betalight. Tritium light sources are most often seen as
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,
