A number of follow-up prospecting techniques for uranium were used in a uraniferous area of New Zealand. Methods included gamma scintillometry, gamma spectrometry and the measurement of the alpha and beta activities and uranium content (determined fluorimetrically) of plants and soils. Statistical analysis of the data, coupled with a study of the work of others in this area, enabled conclusions to be made concerning the relative value of the various prospecting techniques for this area. It was concluded that fluorimetric analysis of plants and soils, gave the most reliable indication of the presence of uranium in the region.
