The radiation exposure from diagnostic medical imaging has increased. The potential risk from radiation exposure of the patient also has increased even though the risk from a small amount of radiation exposure has not been clearly demonstrated. Any medical radiation exposure must be justified and the examinations which use ionizing radiation must be optimized. The education of the referring physician and radiologist are important. However, stronger regulation is essential to control medical radiation exposure. Many national and international organizations have made a significant effort to regulate and monitor medical radiation exposure using guidelines, accreditation, or even laws. Medical radiation exposure must be controlled, and this could be achieved by continuous interest from health professionals and organizations.
Key Words: Radiation protection, Radiation hazard, Computed tomography, Ionizing radiation
