Description

Trap level spectroscopic studies of uranium doped calcium chlorapatite (Ca5(PO4)3Cl) were conducted using electron paramagnetic resonance (EPR) and thermally stimulated luminescence (TSL) techniques. Two glow peaks at 440 K and 495 K were observed (heating rate = 2.5 K/sec.) and their spectral characteristics have shown that UO42- acts as the luminescent centre. Radical ions such as H0, ClO2-, O-, etc. were produced on γ-irradiation at room temperature and of these only H0, thermally unstable beyond 440 K was found to be responsible for the TSL.
