WebTritium is a radioisotope of hydrogen made in small quantities in nature by cosmic rays and decays at the rate of about 5.5% per year. To obtain the quantities required for national defense and civilian needs, it must be produced in nuclear devices or in accelerator. The United States had not produced tritium since 1988.

WebThe kinetics of the turnover of tritium between seawater HTO, biota HTO, and OBT was investigated. HTO in two algae and a mollusk is shown to exchange rapidly with seawater HTO. However, the overall tritium turnover between HTO and the whole-organism OBT is a slow process with a tritium biological half-life on the order of months. WebMar 15, 2024 · The minimum tritium concentrations observed in the Southern Ocean were close to steady-state with known natural tritium deposition. We focused on the temporal evolution of surface (0 to 500 m) tritium concentrations in a selected area of the North Atlantic Ocean (30°N-60°N) where we found the 2016 concentration to be 0.60 ± 0.10 TU … masshire fitchburg ma
