Summary
An intercomparison is made between a collection of five uranium deposits used for neutron fluence determination in neutron activation experiments at Argonne National Laboratory (ANL), Illinois, USA, and a single corresponding deposit from the Institut fuer Radiumforschung und Kernphysik (IRK), Vienna, Austria. The predominant uranium isotope in each of these deposits is U-238. Two methods were used in the study: low-solid-angle alpha counting and the measurement of fast-neutron fission yield ratios. This investigation produced the following calibration values for the IRK deposit: (160.6 {plus minus} 1.7) micrograms from alpha counting and (163.3 {plus minus} 2.0) micrograms from fission ratio measurements. The latter value is a weighted average of twenty-four separate measurements. 13 refs., 2 figs., 4 tabs.
