In order to obtain the data for actual tritium behavior in the room and/or building, a series of intentional tritium release experiments were planed and carried out within a radiological controlled area at Tritium System Test Assembly (TSTA) in Los Alamos National Laboratory (LANL) under US-JAPAN collaboration program. In these experiments, influence of a difference of the release point and a difference of the amount of hydrogen isotope were suggested. In this report, the results of intentional tritium release experiments at TSTA in LANL are summarized. The released tritium was reached a uniform value about 30 40 minutes in all the experiments. The influence of the difference of the release point and the difference of the amount of hydrogen isotope were not seen in these experiments drastically. The initial tritium behavior in the room is also discussed by comparing calculated values with experimental results.
