Yes; these authors should study modern radiobiology.

Hello,

A recent study on cardiac imaging of heart attack patients by Eisenberg et al. in the journal of the Canadian Medical Association (7Feb2011) reports a dose response and a cancer risk of 3% per 10 mSv dose in patients. This seems extremely high.

See the CBC report at http://www.cbc.ca/health/story/2011/02/07/heart-cancer-radiation-tests.html

Any comments?
