Development of an areal density imaging for boron and other elements

Abstract Boron areal densities in pure boron samples were determined using energy-resolved neutron measurements. For non-destructive measurement of boron content, the neutron-energy spectrum was measured with prompt γ -ray activation analysis. It was confirmed that the areal density of samples could be measured with 1% to 10% accuracy for high boron content by neutron energy spectrum analysis. The viability of this analysis is also discussed compared with the traditional quantitative analysis.
