Description
A spectral analysis method is presented to determine depths at which strontium-90 and daughter isotope yttrium-90 arise, based on their bremsstrahlung contributions to the 500-1000 keV energy region. The spectra used to demonstrate this approach were recorded real time, in-situ, in blind tubes with a cerium bromide detector comprised of a Ø10 mm x 9.5 mm crystal coupled to a full-featured MCA Topaz-SiPM digitizer. Theoretical bremsstrahlung accounting for attenuation in-situ is also presented.
