Radiation from imaging diagnostic had caused many detrimental effects to patients. Imaging diagnostic is the largest manmade source of radiation exposure. Dose- response models have aided the study of effects of radiation from imaging diagnostic. Certain imaging tools have caused more radiation hazard towards patients such as computed tomography. Non-ionizing radiation imaging modalities have represented safer alternative. Medical practitioners should adopt as low as reasonably achievable principle during imaging diagnostic to avoid health hazard to patients.
