Fluorescent nuclear track detectors (FNTDs) are suggested for criticality dosimetry of neutrons and photons. The depth profiles of the fluorescent signal from FNTDs after exposure to high doses of broad spectrum neutron fields from four different sources are analyzed using the power spectrum integral (PSI) measured at increasing depths within the Al2O3:C,Mg crystals. The depth profiles are compared to Monte Carlo simulations of energy deposition of recoil protons as a function of depth in aluminum oxide for the same four neutron sources. An algorithm for estimating the median neutron energy and neutron dose correction factors was developed. The application of FNTDs for criticality excursion accidents is discussed.
