Study on a New Label Dosimeter for Radiation Processing
Journal of Isotopes, 2016 In order to monitor the absorbed dose of goods in 60Co γ-rays and electron beams, a new label dosimeter had been developed for dose measurements. The label dosimeter had a multilayer structure, and the core of which was a layer of radiochromic film.

International Journal of Cancer, EarlyView.What's New? The 1986 Chernobyl accident led to widespread radioactive contamination across parts of Europe, with elevated childhood leukaemia rates observed in heavily affected areas of Ukraine. Data on long‐term haematological and other non‐thyroid cancer risk in the general population in heavily contaminated regions, however, remain limited.

Patient Dose Optimisation of Abdominopelvic Protocols During X‐Ray Imaging
Journal of Medical Radiation Sciences, EarlyView.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).

Journal of Physics: Conference Series, 2019 Abstract Measuring radiation exposure has long been a priority in radiation therapy. Over the last 115 years numerous chemical-based dosimeters have been developed to measure radiation exposure. These dosimeters contain either metal complexes or leuco dyes.

Journal of Medical Radiation Sciences, EarlyView.Reducing radiation exposure to staff performing coronary angiography and intervention is an occupational health and safety priority for hospitals. We demonstrate that a larger lead acrylic shield, with lead rubber pleats on the lower edge will reduce radiation exposure to the cardiologist performing the procedure by approximately 40%. We recommend that
