The Ecological Effects using Tritium Fuel in Nuclear Fusion

Nowadays, nuclear fusion reaction taken place in systems as fusion Reactors, are the base of a lot of widespread researches to achievement a new source of energy. Although using these kind of reactors is very beneficial, the optimum usage of them requires sever attention to their effects on human being and his environment. It is shown that the best fuel for fusion reactors is tritium. Tritium is a radioactive isotope of hydrogen with 12.32-year half-life that emits beta radiation. Although its specific activity is relatively weak because of its gaseous state, it can leak easily Its ecological effects should be considered. In all around the world, in order to improving safety and reliability of these reactors, researcher groups expandedly investigate radiation hazards resulting from release of tritium and activation products during normal operations as well as accidental conditions. Some of the most significant results and safety aspects are briefly presented in this paper.
