Photon spectrometry in monoenergetic neutron fields

Photon spectrometry was performed in monoenergetic neutron fields which are produced by nuclear reactions. For this purpose time-of-flight experiments were carried out employing NE 213 liquid scintillation detectors. The photon spectral fluences were obtained by multichannel unfolding using the HEPRO package. The unfolded spectral fluences served to establish routine and simple prompt photon monitoring with a Geiger Müller (GM) counter by linking the GM counter counts to the prompt photon ambient dose equivalent calculated with the spectral fluences and the conversion coefficients.
