Tritium synthesis
WebThus accurate reflection of DNA synthesis can theoretically be obtained with thymidine over a range of different specific activities. However, use of excess tritiated thymidine that has a specific activity of greater than 6 Ci/mM may mean that radiation damage to the cells causes greater loss of counts through cell damage than any increased ...

Liquid scintillation counting (LSC) for tritium compounds was accomplished using a HIDEX 300 SL and ULTIMATE GOLD cocktail (PerkinElmer Inc., Waltham, MA, USA). WebTritium definition, an isotope of hydrogen having an atomic weight of three. Symbols:3H, T See more.
Tritium is an uncommon product of the nuclear fission of uranium-235, plutonium-239, and uranium-233, with a production of about one atom per 10,000 fissions. [16] [17] The main pathways of tritium production include ternary fission of some kind. See more Tritium (from Ancient Greek τρίτος (trítos) 'third') or hydrogen-3 (symbol T or H) is a rare and radioactive isotope of hydrogen with a half-life of about 12 years. The nucleus of tritium (t, sometimes called a triton) contains one See more While tritium has several different experimentally determined values of its half-life, the National Institute of Standards and Technology lists 4,500 ± 8 days (12.32 ± 0.02 years).
