Researchers say nearly one in 10 adults 64 and younger had a heart procedure involving radiation over a three year period. According to a report in the Journal of the American College of Cardiology, than can mean substantial radiation exposure over time.
An advanced type of heart stress test and heart catheterization are considered the biggest contributors to this exposure.
While doctors disagree over how much is too much radiation, there is growing concern that an explosion in the use of medical imaging could be putting patients at risk.
