Optimum Separation

A radiochemical method is given for the determination of Am-241 from the global fallout in sediments. The concept of a concentration step to separate Am-241 from the bulk of the sample (1.2 kg wet) by coprecipitation followed by low energy gamma spectroscopy was investigated. A series of experiments with tracer added was performed to measure the recovery of americium by coprecipitation. Also, a number of real samples without tracer were examined and the conditions for the optimum separation are given. The applied gamma method and the conventional, accurate, but tedious, aplha technique via 243Am, which is usually applied for the determination of Am-241, agreed mostly within 10 %.

In IPEN’s Neutron Activation Laboratory (LAN/IPEN), thin stainless steel sample holders are used for gamma spectrometry in NAA measurements. This material is very practical, but its chemical composition may be troublesome, as it presents large amounts of elements with intermediate atomic number, with attenuation factors for low-energy gamma-rays that must not be neglected. In this study, count rates obtained using different sample holders were compared. To accomplish that, an Am-241 source, with 59-keV gamma emission, was used so that low-energy gamma attenuation differences can be determined. Moreover, in order to study the energy dependence of these differences, a Ho-166m source was also used. From these results, it was possible to analyze the experimental error associated to the variations between sample holders, with the aim of introducing an addictive term to the uncertainty analysis of comparative Neutron Activation Analysis results.
