RE: comparing individual and collective doses
Mike
We had many long discussions on this when we developed/wrote? NCRP
Publication 121 but did not resolve it completely. My take on it was that
the individual dose should be used to judge if a practise was acceptable and
collective dose on whether it was ALARA.
That is, ALARA does not apply to individual dose.
What this means for regulations depends on the "regulator" :)!

Subject: comparing individual and collective doses
Dear RadSafers
I have often read that when applying the ALARA principle, it is important
to consider both individual and collective dose equivalents. Is there any
guidance on how to compare these two? For example, how would one compare n
mrem to the most exposed individual member of the public with a collective
dose of n rem distributed evenly among a million people?
