This article contains the current situation in respect to the environmental concentrations of anthropogenic and natural tritium. There are presented and analyzed domestic standards for НТО of all Radiation Safety Standards (NRB), as well as the regulations analyzed for tritium in drinking water taken in other countries today. This article deals with the experience of limitation of tritium and focuses on the main problem of rationing of tritium — rationing of organically bound tritium.

Assessment of committed effective dose and the uncertainty of its calculation for different variants of 3H intake: 1) homogeneous and chronic, 2) single, is considered by the example of internal tritium doses that workers had got. It has been shown that in case of conditional measurement of 3H concentration in urine sample the estimate of tritium dose may vary within two orders of magnitude in the 95% confidence interval. The most effective way to reduce the range of uncertainty of dose estimation is to replace a quarterly monitoring with a monthly one. It leads to reduction of the range of uncertainty by one order of magnitude.
