Anomalous radioactivity highlighted the Lake Tyrrell area as a potential mineral exploration target and prompted a 5-year study of its groundwater geochemistry. The groundwaters are very acid (median pH=4.2) and saline (median ionic strength ( I ) =

Acidic-saline groundwaters in the region of Lake Tyrrell carry unusually high concentrations of trace metals but the brines of Lake Tyrrell do not have the concentrations that would be generated by evaporation of those groundwaters. This study invest

Many natural radionuclides have been measured in regional groundwater, acid spring waters and brines in the vicinity of Lake Tyrrell, Victoria. The concentration of nuclides within the U and Th decay series range over several orders of magnitude. The

Uranium series radionuclides were determined in a sample collected from a rainwater puddle at the Ranger Uranium Mine (Northern Territory, Australia). The 1 l sample contained 0.25 g of uranium with a 234U/238U activity ratio of 1.07. The activities

Water samples from saline seepages in the south-western Yilgarn Block of Western Australia contain high activities of the four naturally-occurring radium isotopes. Activities of up to 310 pCi l for 226Ra and 1720 pCi l for 228Ra were measured and the
