This study investigates the development of epoxy-resin composites reinforced with coral-derived calcium carbonate (CaCO) fillers for enhanced radiation shielding and mechanical properties. Leveraging the high calcium content and density of coral, composites were prepared with filler weight fractions of 0%, 25%, and 50%. SEM and EDS analyses revealed that higher filler concentrations (50%) increased particle agglomeration, affecting matrix uniformity.

This study explores the development and efficacy of eggshell-derived particle composites with epoxy resin for enhanced radiation shielding applications. Eggshells, primarily composed of calcium carbonate, were processed into particles of three sizes: small, medium, and large. These particles were incorporated into epoxy resin at a 50% weight ratio and characterized using a Laser Particle Size Distribution Analyzer.

In medical practice, iodine contrast media are necessary for diagnostic techniques. However, it comes with a potential risk to the patient in the form of allergic reactions. The aim of this research is to study the effects of iodine contrast media on endothelial cells in an system at various concentrations, specifically investigating their impact on cell viability, cell cycle, and apoptosis in the treated cells within the field of diagnostic radiology.

Iodine contrast agents are essential for diagnostic purposes in radiology and have significant medical benefits. However, they pose a risk of causing allergic reactions or adverse cellular effects. In this study, we examine the effects of iodine contrast agents (Iopamiro 370, Ultravist 370, Visipaque 320, and Optiray 350) on cellular functions of human peripheral blood mononuclear.

The COVID-19 pandemic has resulted in a large increase in the number of patients admitted to hospitals. Radiological technologists (RTs) are often required to perform portable chest X-ray radiography on these patients. Normally, when performing a portable X-ray, radiation protection equipment is critical as it reduces the scatter radiation dose to hospital workers.

The purpose of this study was to perform in-vivo dosimetry using a diode rectal dosimeter in phantom and compare the dose delivered to the rectum between the dose measured by the diode dosimeter and the dose calculated by the treatment planning system in cervical cancer. The PTW T9112 diode detector calibrations were performed to find the correction factor. Then the calibrated diode detector was used to measure the radiation dose received in the rectum area in the in-house pelvic phantom.
