-49- TABLE 4.3(b) RADIUM CONCENTRATIONS BORE RN RADIUM 226 (in mBq/L) (a) In Water (b) In residue 14249 7 < 1 14853 10 < 1 Recommended levels for radionuclides in irrigation water are those set out for potable supplies (Environmental Protection Agency, Victoria, 1983). The guideline value for potable water (NHMRC 1987) is gross alpha activity of 100 msq/L. As Radium 226 is the most restrictive naturally occurring radionuclide with respect to water supplies, it can be safely assumed that gross alpha activity is well below the guideline value. 4.4 ISOTOPE CHEMISTRY 4.4.1 Tritium And Deuterium Tritium and deuterium determinations on samples obtained during Stage 2 of the 1984/85 investigation were carried out by the Australian Atomic Energy Commission at Lucas Heights, under the supervision of Dr G. E. Calf. Results are shown at Table 4.4.1. In all samples tritium values were very low, indicating - that waters sampled are older than 25 years, and probably older than 50 years since recharge. A - comparison of sampling depth against standing water level for each bore sampled shows that all of the samples were obtained from below, and in many cases - several metres below, the water table.
