[ RadSafe ] medical scans and risk

[parthasarathy k s]

Friends,

HPS should have waited till  Dr. Zanzonico's model -calculations and  related arguments have been published in a peer- reviewed journal. There is no overwhelming evidence which supports any model other than LNT though the prescription of this model started as a convenient tool in radiological protection. The issue is unlikely to be settled soon.

Regards
K.S.Parthasarathy

I completely agree with the conclusion in this piece, but I think that
the net benefits are actually even higher when viewed in Life-Years
lost, as many of the X-ray, CT, etc. procedures have a (theoretical)
risk that is in the distant future (in the tens of years, often),
whereas the life saving/improving benefit much sooner; in the several
 of
hours, in the case of trauma.  Hard to fit them on the same scale.
