Determination of gamma dose and thermal neutron fluence in BNCT beams from the TLD-700 glow curve shape

Abstract

Abstract The measurement of both gamma dose and thermal neutron fluence in a BNCT gamma–neutron mixed-field can be achieved by means of a single thermoluminescence dosimeter (TLD-700), exploiting the shape of the glow-curve (GC). The method is based on simple algorithms containing parameters obtained from the TLD-700 GC and requires the gamma calibration GC (for gamma dose measurement) or the thermal neutron calibration GC (for neutron fluence measurement) and moreover the GC of a TLD-600 exposed to a BNCT field, uncalibrated. Some results are reported, showing the potentiality of the method.
