Tritium concentration in well water of Daedeog area

Tritium concentrations in well water of Daedeog area and its vicinity were measured by means of electrolytic enrichment technique and liquid scintillation counting method. Samples were taken from six different wells spread around Daedeog Science Town at least ten kilometers away from each other, so as not to have any possible influence from other water sources or streams. The tritium enrichment factor in the electrolytic process was determined using standardized water of known activity. Results show that the mean value of tritium concentration in well water of this area is 41.60+-2.52 TU with maximum and minimum of 44.33+-2.64 TU and 39.20+-2.65 TU, respectively, as of September 1981, which are quite reasonably comparable with 40 TU measured by Fireman and Schwarzer for well water.
