Diagnostic radiology procedures, such as computed tomography (CT) and X-ray, are an increasing source of ionising radiation exposure to our community. Exposure to ionising radiation is associated with increased risk of malignancy, proportional to the level of exposure. Every diagnostic test using ionising radiation needs to be justified by clinical need. General practitioners need a working kno...

This paper summarizes technological advances in diagnostic radiography, fluoroscopy and computed tomography, mainly the developments in digital detectors and helical CT scanners with multiple-row detectors. It reviews dosimetric concepts and presents the most up-to-date information on the global patterns of use of radiological modalities as well as the trends in diagnostic medical exposure dose...

Introduction: The rapid development of wireless telecommunication technologies over the past decades, has led to significant changes in the exposure of the general public to electromagnetic fields. Nowadays, people are continuously exposed to different sources of electromagnetic fields such as mobile phones, mobile base stations, cordless phones, Wi-Fi routers, and power lines. Therefore, th...
