Doctors are exploring ways to reduce the amount of radiation exposure from medical imaging tests in light of renewed concerns about the cancer risk, according to research presented at a radiology conference. Radiologists have been working for several years to reduce unnecessary radiation exposure in children, whose growing bodies are more sensitive to radiation than adults', says Richard Morin, chairman of the American College of Radiology's Safety Committee. But Morin says other doctors also need to do more to protect patients, such as referring them for imaging tests only when they're really necessary.
