ICRP/NCRP Risk Factor Use

[Michael S Ford <MFORD@pantex.com>]

Question for the group:

Given a risk factor of 4 E-2 fatal cancers per Sv and a collective dose
of 1 Sv for a particular group, how is the resulting 4 E-2 fatal cancer
risk interpreted?

4 E-2 fatal cancer risk for each person in the group OR
4 fatal cancers per 100 persons in the group, 40 per 1000, etc.?

I had read previously -- ICRP and NCRP -- that the fatal cancer risk
values only applied to populations not to individuals, but ICRP 26
para 60 talks about *individuals* specifically.

Thanks in advance for any information you may provide!
