Medical Imaging and Ionizing Radiation Effects on Human Health

Abstract:
Ionizing radiation that is used in medical imaging releases free radicals. These radicals can interfere with the molecular chemical bonds that is responsible for regulating the cellular function inside the cell. The interaction between free radicals and the molecules inside the cell might lead to genetic mutations in the DNA and it can damage cellular enzymes leading to the proliferation of cancer cells. In the United States, 50% of the environmental exposure to ionizing radiation is mainly attributed to medical imaging. Computed tomography (CT) scans are the main source of X-rays, a form of ionizing radiation. The purpose of this project is to present an overview of the main reasons for exposure, explaining the possible future effects of ionizing radiation on human health, enlightening the imaging modalities with ionizing radiation, addressing the population at risk, and explaining the main principles and recommendations to avoid and limit the exposure to ionizing radiation. _
Key Words: Computed tomography (CT) scans. X-rays.
