The radiation exposure of U.S. patients from medical tests has increased sixfold since 1980, according to a new study. About 380 million diagnostic and interventional radiological tests were conducted in the U.S. in 2006, in addition to 18 million nuclear medicine procedures. Radiation exposure from medical tests "is essentially unregulated" and may be so high due to emergency room physicians who order scans to avoid lawsuits, the lead author said.
