Effect on Worker and Environment in Survey of Source Term for Decommission Tritium Laboratory

The survey of the source terms was carried out before a tritium laboratory decommission. The radiation protection for the action was reported based on the lab condition, and the radiation dose of the worker and the people who lived around were analyzed. The results show that the investigation has a little influence for the lab environment. During the actions the maximum value of radiation internal dose for worker is 0.111 mSv from HTO, and it’s 7.750×10^-5 mSv for the people who lived around the lab.
