Review of the thermoluminescent dosimetry method for the environmental dose monitoring [PDF]

Nuclear Technology and Radiation Protection, 2021
Passive solid state dosimeters, such as thermoluminescence dosimeters, provide integrated measurement of the total dose and are widely used in environmental monitoring programs. The objective of this paper is to provide a comprehensive review on

Characterization of Thermoluminescent Dosimeters for Neutron Dosimetry at High Altitudes [PDF]

Sensors, 2022
Neutrons constitute a significant component of the secondary cosmic rays and are one of the most important contributors to natural cosmic ray radiation background dose. The study of the cosmic ray neutrons’ contribution to the dose equivalent received by

Integrating measurement and simulation for evaluation of patient-specific whole-body dosimetry in clinical BNCT. [PDF]

Med Phys
Abstract 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.

Investigation of Thermoluminescence Characteristics and Kinetics of Natural Obsidian. [PDF]

Luminescence
Thermoluminescence (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 ...

The Spinning Manny Indexed Overlay System for VMAT total body irradiation. [PDF]

J Appl Clin Med Phys
Abstract Purpose While modern intensity‐modulated techniques for total body irradiation (TBI) offer superior organ sparing and improved dose coverage compared to conventional TBI, their complexity has limited widespread adoption. Specifically, when treating individuals with Volumetric Modulated Arc Therapy (VMAT‐TBI), a transition between the head ...

Sensitivity and Performance of Uncooled Avalanche Photodiode for Thermoluminescent Dosimetry Applications [PDF]

Sensors
Detecting extremely low light signals is the basis of many scientific experiments and measurement techniques. For many years, a high-voltage photomultiplier has been the only practical device used in the visible and infrared spectral range. However, such

Patient Dose Optimisation of Abdominopelvic Protocols During X-Ray Imaging. [PDF]

J Med Radiat Sci
This 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).
