Radiometric techniques of determining the nickel content in lateritic ore samples are described. In some of the methods proposed a semiconductor detector and a multichannel pulse height analyzer are required. In another technique simple portable equipment with a proportional counter was used. Calculation methods of correction for matrix effects were applied, in combination with measurements of the fluorescence to scatter ratio and the use of edge filters.
