Radiologic technologists and ancillary staff who work with or near ionizing radiation face possible short- and long-term effects of occupational radiation exposure. Further, radiologic technologists must minimize unnecessary exposure that risks the patient's safety, while achieving the best possible image or outcome. This article reviews occupational dose limits, dose calculation, devices used to measure exposure, and safety best practices that can help technologists keep radiation exposure "as low as reasonably achievable" for them and their patients. The article also discusses the appropriate use of mounted and mobile equipment, personal protective equipment, and safety features on imaging equipment to minimize unnecessary radiation exposure.
