In this study, tritium transfer from foods Organic Bound Tritium or tritiated water to DNA was measured by E. coli cell and tritium concentration in DNA during fusion plant operation was estimated. Measured tritium concentration in DNA was much lower than estimated value based on the atomic ratio of culture medium. In addition, contribution of organic bound tritium in our food to calculated tritium concentration in DNA was greater than the contribution to tritium dose.
