ORLANDO, Fla. — The first large study to examine cumulative radiation exposure from medical imaging after a heart attack has found that the average patient receives the equivalent of about 725 chest X-rays before leaving the hospital. That’s about one-third the maximum radiation dose allowed for a nuclear power plant worker in a given year.
Whether this is enough radiation to be a cancer risk is unclear, the researchers say, but the information should be sobering for physicians and patients.
