Investigation of Thermoluminescence Characteristics and Kinetics of Natural Obsidian. [PDF]
LuminescenceThermoluminescence (TL) properties of natural obsidian from the Aksaray region were investigated under beta irradiation. The study identifies optimal grain size, evaluates kinetic parameters via Tm–Tstop and computerized glow curve deconvolution (CGCD) methods, and demonstrates the material's potential for low‐dose environmental and personal radiation ...

Integrating measurement and simulation for evaluation of patient-specific whole-body dosimetry in clinical BNCT. [PDF]
Med PhysAbstract Background Boron neutron capture therapy (BNCT) is a treatment modality that utilises high intensity neutron beam in combination with a boron drug to target cancer cells at the cellular level. Despite decades of research in this field, there are very few reports on out‐of‐field patient dose of BNCT.

Patient Dose Optimisation of Abdominopelvic Protocols During X-Ray Imaging. [PDF]
J Med Radiat SciThis study evaluates organ doses in abdominopelvic radiography for both erect and supine positions, addressing dose optimisation concerns in Ghana. Using CalDose X and thermoluminescence dosimeters, organ doses and image quality were analysed, revealing significant dose reductions with optimised exposure parameters (70 kVp, 10 mAs, 110 cm FDD).

Quantitative Assessment of the Effects of Scatter Radiation on Image Quality During Extremity Radiography at a Leading Tertiary Hospital in Ghana: An Experimental Pilot Study. [PDF]
Health Sci RepABSTRACT Background and Aims There is a potential increase in scatter radiation during extremity radiography, where radiographers may divide the detector to obtain multiple images on one film. This study assesses the impact of scatter radiation on image quality (IQ) during the dividing receptor technique in extremity radiography at the Korle‐Bu ...

Application of MCP-N (Lif: Mg, Cu, P) TL detectors in monitoring environmental radiation [PDF]
Nuclear Technology and Radiation Protection, 2004 Thermoluminescent MCP-N detectors based on LiF:Mg,Cu,P are by about 2 orders of magnitude more sensitive than TLD-100 detectors based on conventional LiF:Mg,Ti, which makes it possible to use them in short-term monitoring of ionizing radiation in the ...

Validation of the stamping method for CaSO4:RE + Teflon® pellets production
Brazilian Journal of Radiation Sciences, 2015 The IPEN method for the CaSO4:RE + Teflon® production, developed and patented at the Dosimetric Materials Laboratory – LMD/IPEN in the earlier 1980’s, [1] is highly time-demanding, so that the use of the stamping method, already widely industrially ...
