    An empirical scheme based on the concentrations of uranium and the three alpha-emitting radium isotopes 226Ra, 224Ra and 223Ra is proposed for rating the significance of ground waters with respect to uranium exploration. The scheme has been developed from the results for over 200 water samples from the vicinity of known uranium deposits and radium anomalies in areas of Australia with climates varying from arid to tropical. The scheme uses relative levels of the four factors to rate the potential of a sample as good, possible or poor. An example of the use of the system in ground-water exploration in the Frome Embayment, South Australia, is presented to illustrate the value of the scheme in rejecting falsely anomalous samples with high uranium concentrations whilst detecting nearby uranium mineralization from drill holes not intersecting mineralization.
