Tritium is a natural cosmogenic nuclide and omnipresent in natural waterbodys. However, man made nuclear activities have strongly increased the global inventory. The talk will cover natural and anthropogenic sources, the radioecological modelling of tritium migration in the environment and dose assessment to humans. Tritium will be compared to other radionuclides with respect to peculiarities of uptake and biological half life in the human body. Specific damage to tissue is rather low, due to its limited beta decay energy. This leads to high exemption limits for handling and high specific activities for clearance and discharge during the operation of nuclear facilities. Regulatory limits and dose coefficients as suggested by WHO, IAEA and ICRP as well as German legislation are discussed. Finally, the discharge of contaminated water from the Fukushima Daichi site will radiologically be set into perspective. [mehr]
