The existence of radioactivity linked to the heavy-bearing minerals in building materials—such as granite—has increased attention extraction procedure. Granite rocks play an essential economic role various areas Egypt. Thus, this study intended detect 238U, 232Th, and 40K activity concentrations examined granite samples determine corresponding radiological risks associated with granite. studied...
This study presents the results of ambient radioactive radiation, radiation health hazard indices and excess lifetime cancer risk estimation around radiological sections in Federal Teaching Hospital Gombe, Gombe State, Nigeria using a well calibrated Rados-200 meters Global Positioning System (Garmin 765). The mean annual outdoor equivalent dose 0.078 mSv/y. was measured. Mean effective doses 0...
Natural history studies have identified factors that predict evolution to multiple sclerosis or risk of disability accumulation over time. Although these studies are based on large multicentre cohorts with long follow-ups, they have limitations such as lack of standardized protocols, a retrospective data collection or lack of a systematic magnetic resonance imaging acquisition and analysis prot...
