Medical Uses for Radiation

Medical Uses. There are many uses of radiation in medicine. The most well known is using x rays to see whether bones are broken. The broad area of xray use is called radiology. Within radiology, we find more specialized areas like mammography, computerized tomography (CT), and nuclear medicine (the specialty where radioactive material is usually injected into the patient).
