Doing More With Less

Medical radiation doses dropping.  I have an issue with this statement about the risks:

"To be on the safe side of this debate, we assume that there is some small increase in cancer risk from even low doses of radiation and so try to keep the dose levels as low as reasonably possible, while at the same time making sure that the image quality is sufficient to provide an accurate diagnosis."

No, this is not about being on the "safe side" of the debate.  It's about being on the evidence-based side of the debate.  We know radiation can ionize DNA, and that DNA damage is not always detected or repaired correctly regardless of the dose.  So we conclude there is a certain risk which we estimate from many different avenues.
