Routine releases of tritium to the atmosphere from the Savannah River Plant (SRP) have averaged 5.12 x 105 curies per year during the period 1974 to 1977. Patterns of tritium dispersion in the environment surrounding SRP indicate a power law relationship between air concentration and distance from the source. The relationship between the concentration of tritiated water in vegetation and distance is more complex. A model of the tritium dispersion and cycling in the environment explains the dispersion patterns in terms of the ratio of tritiated hydrogen to tritiated water, climate, and vegetation characteristics. The annual variation in the environmental patterns around the SRP is almost completely determined by the fraction of tritiated hydrogen in the release.

During 35 years of operation of the Savannah River Site (SRS) there have been a small number of inadvertent tritium releases to the atmosphere. After detection of the releases by stack monitors, field crews were dispatched to determine the concentration of tritium in the environment. The objective of the measurement was to verify environmental concentrations calculated by dose assessment models. Air samples were used to verify the concentration levels and tritium forms during the plume passage. It was not feasible to take enough samples in the plume path to determine the two dimensional distribution of tritium concentration in the plume. However, the ground level distribution was very well reflected vegetation samples. Therefore, it is unusually possible to determine plume shape, plume width, and the relative maximum concentration as the plume moves downwind from the vegetation samples. In eight of the nine releases studied, the monitoring data allowed comparison with atmospheric transport models.

The BIOMASS (Biosphere Modelling and Assessment Methods) programme seeks to improve methods of assessing the impact of radionuclides in the environment (any man-made or natural element that emits radiation and that may cause cancer after long term exposure through drinking water). This report describes the results of studies undertaken by the Tritium working group established to identify gaps in modelling approaches regarding the transfer of radionuclides in particular parts of the biosphere of potential radiological significance. It discusses six model test exercises and the field sampling programme undertaken to environmental spread of tritium in long term atmospheric and sub-surface sources.
