Tritium range in tissue
Did you know?
Tritium has been used for biological radiometric assays, in a process akin to radiocarbon dating. For example, in one paper, [ H] retinyl acetate was traced through the body of Sprague-Dawley rats. The beta particles emitted by the radioactive decay of small amounts of tritium cause chemicals called phosphors to glow. Webthe range appears to be 20-80 days for most of the radioactive tritium and 280-550 days for a smaller component. It has been estimated that total incorporation of radioactive tritium …
WebWhen it has lost the whole of its initial energy, it comes to the end of its range. The greater the initial energy of the beta particle, the greater its range. The range is inversely proportional to the density of the material. The most energetic beta rays have a range of a few millimetres in tissue. View chapter Purchase book Webof mammals is shown to be 15 to 40% less than in whole tissue. The kinetics of tritium incorporation from oxide (HTO) and its retention in DNA of hemopoietic tissues were …
WebTritium is also produced as a ternary fission product, within the fuel rods of nuclear reactors, at a rate of 1–2×10. 4. Ci/1,000 megawatts electric. (Although much of the tritium produced in this manner remains trapped within the matrix of the fuel rods, estimates suggest that recovery of this tritium could reach levels of 1×10. 6 . Ci/yr.)
