Tissue-equivalent detector photon response matrix

As an integral part of an investigation into the adequacy of existing dosimetry systems and survey instruments, photon spectra at two locations around a boiling water reactor (BWR) needed to be determined. One of these areas was adjacent to the turbine where 16N photons are expected; the other was near the residual heat removal system where 60Co photons were anticipated to dominate the spectrum. To perform the spectral measurements required, a response matrix for unfolding Compton recoil spectra was required. This paper details the generation of that matrix
