AW: [ RadSafe ] Basis for radiation dose limits - organ specific

[Rainer.Facius at dlr.de]

Thomas:

Limits for organ specific doses are determined so as to PROHIBIT 'deterministic' i.e. threshold (early) effects in an organ such as erythema for skin or cataracts for the eye. Whole body effective dose is designed to CONSTRAIN cancer mortality below a level deemed acceptable - of course under the questionable assumption of the LNT postulate(!).

Betreff: [ RadSafe ] Basis for radiation dose limits

Not having ICRP 60 available, I wanted to ask the group what is the basis for the difference in limits for whole body, skin, eye, etc.

I know the fundamentals, but I am trying to explain this to a non-technical person.

Thank you in advance for your response.
