“…Using electrolysis of water to enrich the tritium concentration, the discovery of natural tritium in the environment roughly coincided with the beginning of the nuclear age (Grosse and others, 1951;Giletti and others;1958). Before nuclear testing, tritium found in the environment resulted from accretion from the sun or cosmic-ray spallation, the latter of which was thought to be the dominant process (Wilson and Fergusson, 1960;Nir and others, 1966;Teegarden, 1967). The cosmic-ray production probably kept a steady-state burden of tritium of 3-4 kilograms (kg) on the Earth's surface (Lal and Peters, 1967).…”

“…Natural tritium production per unit time and per unit area at the earth's surface is estimated to occur at a rate of approximately 0.1 to 1.3 tritium atoms/cm 2 /s, with the most probable values occurring around 0.5 to 1.0 tritium atoms/cm 2 /s [7][8][9][10]. The turnover of tritium is very fast, except where it is fixed in glacier ice or groundwater, and when it is incorporated into organically bound tritium in organisms [11].…”

The assessment of nuclear objects sites in Lithuania, including groundwater characterization, took place in the last few years. Tritium activity in groundwater is a very useful tool for determining how groundwater systems function. Natural and artificial tritium was measured in 8 wells in different layers (from 1.5 to 15 meters depth). The results were compared with other regions of Lithuania also. The evaluated tritium activities varied from 1.8 to 6.4 Bq/L at nuclear objects sites in Lithuania and they are coming to background level (1.83 Bq/L) and other places in Lithuania. The data show, that groundwater at the nuclear power objects sites is not contaminated with artificial tritium. In this work, the vertical tritium transfer from soil water to the groundwater well at nuclear objects site was estimated. The data show that the main factor for vertical tritium transfer to the well depends on the depth of wells.
