Tritium concentrations in surface waters of Indian ocean and in lakes around Indian station Maitree in Antarctica

192-195Spatial distribution pattern of tritium in the surface waters of Indian Ocean reveals a minima at the equator, a primary peak of about 15 TU between 30 degrees S'and 40 degrees S and secondary peaks of about 10 TU between 50 degrees S to 67 degrees S latitudes. The asymetric nature of the tritium distribution pattern is discussed in relation to hydrographic characteristics of the region. Tritium concentrations in some fresh water samples collected near around Indian station Maitree are also presented
