This study aims to investigate the effects of different nuclear radiation fields on an optically stimulated luminescence (OSL) dosimeter using Al 2 O 3 :C material. The Al 2 O 3 :C material was exposed to α -and β -particles and γ -photons, and the luminescence signals were measured by stimulation with a blue light emitting diode. It is concluded that the OSL technique is suitable for obtaining an adequate blue light stimulated luminescence signal in α , β , and γ radiation fields, and if the source activity was low, the statistical distributions were large.

Optically Stimulated Luminescence (OSL) trap parameters can only be reliably determined through the detailed analysis of OSL decay curves. In this study the kinetic parameters of a blue-light stimulated luminescence (BLS) decay curve from Al 2 O 3 :C sample irradiated at 0.1, 0.15, 0.2, 0.4 and 0.6 Gy beta doses were obtained using the same basic methods with some modifications applied and also by using our suggestion: Active-OSL Approximation (AOSL). The results were compared with those of other studies on the trap parameters of Al 2 O 3 :C material.

“…The measured CW-OSL decay curve has an approximately exponential form. Deconvolution of luminescence decay curve from different samples has been studied by many researchers (Bailiff and Poolton, 1991;Barnet, 1994, Smith andRhodes, 1994;McEwen and Chen, 1997;Tanır and Bölükdemir, 2010). Most of the studies have shown that there are several overlapping OSL signals, each having different detrapping constants (Bailey et al, 1997;Adamiec, 2005;Kitis et al, 2002).…”

It is clear that humans are exposed to ionizing radiation both of internally or externally in radiotherapy. The determination of ionizing radiation dose in human blood has been previously performed by us using optically stimulated luminescence technique. OSL technique is based on measuring the luminescence intensity from a sample that has been exposed to ionizing radiation. In this study, the detrapping constants for human blood samples were investigated using Curve-Fitting, Active OSL-Approximation and Linear Modulation techniques. The Active OSL-Approximation was based on the radioactive decay law of successive disintegration. It allows obtaining the peak forms of luminescence signal. It has been observed that the decay rates for blood sample exposed to different radiation doses were changed with dose. AOSL-Approximation is appropriate for separating the peaks that correspond to decay rates.
