As many as 4 million adults in the U.S. under the age of 65 are being exposed to high, potentially cancer-causing levels of radiation from medical imaging tests of unproven value, according to a new government-funded study.
Analysis of insurance claims for close to 1 million non-elderly adults found that roughly two-thirds had at least one medical imaging test resulting in radiation exposure and one-fifth were exposed to moderate-to-high doses of radiation during the study period.
