• To understand behavior of organically bound tritium (OBT) in the environment, concentration rations of OBT to tissue free water tritium (TFWT) were compared between a rice plant grown under equilibrium condition and a pine tree grown under non-equilibrium condition. The OBT to TFWT ratio of rice was 0.69±0.38 as an average for the polished rice harvested in the whole Japan in 1985. On the contrast, the ration of pine needles collected near nuclear facilities changed with time between 1 and 2. It is concluded that the concentration ratio of OBT to TFWT in the plant keeps less than unity under the quilibrium condition, but it is possible to become larger than unity under the non-equilibrium condtion, because OBT has longer retention time in the plant than TFWT.
