WebTritium concentration in soft tissue and the associated dose to these tissues is generally uniform and dependent on the water content of the tissue. Because the water content in the body turns oNcr frequently. tritium is rapidly cleared from tissues. What recommendations has the Environmental 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.) Webconcentrates to a very high degree in tumor tissue so that its radiation effects are mainly centered on that tissue, sparing the associated normal organs.

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.
