And yet, this Harvard Medical School link (not a report, not peer reviewed, but whatevs) clearly states that one CT scan of 4 to 18 mSV increases cancer risk by 0.7%, which is higher than the increase of 0.5% from 100 mSV exposure over a greater period of time. So, no. The Harvard Medical School link does not refute in any way my point. In fact, it supports my point.
