Behavior of tritium permeation through paint membranes was experimentally investigated for clarification of mechanism of tritium transfer through hydrophobic paints coated on a concrete material. From the results of measurement of tritium permeation rates, it was found that tritium permeated through epoxy and urethane paint membranes as the form of a HTO molecule, and that diffusion in their paints was the rate-determining step. The permeation rates through concrete materials coated with the paints were much slower than those through the paints only. Hence, resistance of tritium diffusion through interface between a concrete material and paint was clarified to be most effective in the overall tritium transfer process.

为阐明氚在混凝土材料表面涂敷的疏水涂料中的迁移机理，对氚在涂料膜中的渗透行为进行了实验研究。从氚渗透率的测量结果，它被发现，氚渗透通过环氧树脂和聚氨酯涂料膜作为HTO分子的形式，并在他们的油漆中的扩散是速率决定步骤。通过涂有涂料的混凝土材料的渗透速率比仅通过涂料的渗透速率慢得多。因此，通过混凝土材料和油漆之间的界面的氚扩散阻力被澄清为在整个氚转移过程中是最有效的。
