After a myocardial infarct most people in the West get about 5mSv in the first year just from tests. There is an increased risk of cancer in these patients in the next five years.
We need to think more about this. At present there is no system in place to record a person's accumulative radiation from medical imaging. No one seems to care about the radiation from air travel.
As the atmosphere degrades our annual radiation from gamma rays will worsen.
