Medical radiation can be dangerous if it’s not used correctly. Radiologic technologists are responsible for using radiation safety techniques to protect patients, themselves and their coworkers. First, they use proper equipment settings to deliver the smallest radiation dose possible in order to obtain a quality medical image. Second, they make sure everyone involved in the procedure uses proper shielding to protect them from unnecessary radiation, which can include lead aprons, lead gloves, lead shields and lead-lined glasses and headwear. And third, radiologic technologists position patients properly in order to get the image right the first time because additional images can expose the patient to extra radiation.
