Abstract
A neutron activation method of analysis for the determination of alumina and silica in geological samples has been developed and applied to some geological standards. Samples of about 4 g /in Cd shield/ were irradiated in the immediate vicinity of a 5 Ci Pu−Be source. Gamma spectra were acquired using a 7.5 cm × 7.5 cm NaI/Tl/ detector. The irradiate-transfer-count sequence was repeated five times in succession, counts being taken cumulatively. Recycling of the sample produced improved counting statistics and better reproducibility.
