Isotope geochemistry this reason, enrichments are typically reported in "per mil" (‰, parts per thousand). These enrichments (δ) represent the ratio of heavy isotope to light isotope in the sample over the ratio of a standard. That is, Hydrogen isotope biogeochemistry Carbon has two stable isotopes, C and C, and one radioactive isotope, C. The stable carbon isotope ratio, "δ"C, is measured against Vienna Pee Dee Belemnite (VPDB). The stable carbon isotopes are fractionated primarily by photosynthesis (Faure, 2004). The C/C ratio is also an indicator of paleoclimate: a change in the ratio in the remains of plants indicates a change in
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,
