[1N15] Tritiumu release from graphite containing tritium at ambient temperature

*Masanori Hara1, Masao Matsuyama1, Kenji Okuno2 (1. University of Toyama, 2. Shizuoka University)

Keywords:tritium, graphite, evolution, liquid

Various graphite samples were irradiated by tritium ion. The samples were immersed in pure water or an organic solution (liquid scintillator). The tritium evolution behavior was measured for several years. The tritium evolution into pure water was observed up to 4000 hrs. On the other hand, the tritium concentration in an organic solution was remained for our measurement period.
