  •  Most dose-response curves are not usually linear (5+ / 0-)

    I would think that extrapolating the dose response curve, which is linear at higher doses down to the very low dose range, which cant easily be studied experimentally, is a very conservative model.  It is probably the case that at very low radiation doses DNA repair mechanisms are efficient enough to repair any radiation damage, making the risk close to non-existent.  But I guess with the lack of empirical evidence it is best to estimate risk on the conservative side.

    •  Many dose curves are threshold (4+ / 0-)

      or in fact quadratic, meaning there is less risk at lower levels (quadratic) or no risk (threshold).  

      The LNT model is the least conservative one that I know, and while I'm not sure I agree with it, I still try and keep my exposure As Low As Reasonably Achievable (ALARA).  I guess it is generally better to be conservative when it comes to health and unknown factors.
