Thermoluminescence dosimetry of mixed neutron-gamma fields using CaF2:Mn pellets

Abstract

The measurement of fast neutrons in mixed neutron- gamma (n- γ ) field by used CaF2:Mn (pellets) had adiameter of (1 x 1 x 6 ) mm and thickness of 1 mm and using hydrogenated materials as converters of neutron to ; recoil protons the disc were by irradiation to the neutron source (Am241- Be) with flux of 4.5 x 105 n/cm2, with different time the dose were we have obtained an increases to 90% in the TL signal when we used the converters. So the neutron and gamma dose were resolved .
