RE: ICRP 2 standard
Along the same topic Prof. Lindell, invited by NCRP (1988) and gave the
Taylor Lecture (#12) titled "How Safe is Safe Enough?" In this paper, Bo
put risk into formula and showed his quantitative values as for
cost-effective analysis. It is an excellent reference if you are interested.

Prof. Bo Lindell who is the recipient of the first Sievert award, presented
at international congress on radiation protection IRPA-9 in Vienna (April
1996), one of the most important paper on risk evaluation and
decision-making. The main point of his lecture was that there are no
acceptable risks only acceptable practices, and that communication with the
public needs to be a higher priority in the field of radiation protection.
Bo's paper, RISK EVALUATION AND DECISION MAKING, explains with admirable
competence many of our divergences. One point in the Bo's paper is Attention
to Attitudes, and he point out that there are a number of well known factor
that form our attitude and they influence our risk perception, but this view
may be to narrow since they influence our attitude to more than just the
risk, and Bo explains the most important factor. Probably many of you have
attended that risk evaluation and decision making symposium and have the
Bo's paper, however if someone has not and is interested, it will be a
pleasure to send it.

What about the 15 mrem/year EPA limit for groundwater, the 25 mrem/year
decommissioning limit (10 CFR 20, Subpart E), or the ZERO allowable
contamination limit for the free release of materials by a licensee (10 CFR
20,
Subpart K, as interpreted in NRC, HPPOS-221: "The regulations applicable to
nuclear power reactor licensees do not provide for the release of materials
that
are known to be radioactively contaminated at any level...")?
I'm not saying that those who laid the groundwork for such unreasonable
public
concern did so "for the purpose of getting big bucks." However, there was a
natural bias to think that radiation hazards are different from any other
hazards, even chemical carcinogens. This guilty until proven innocent
approach
to radiation protection is where we screwed up. If we took that approach to
everything, we'd never get out of bed in the morning, and it was naive to
not
anticipate the effect of such policies on the public. I'm not questioning
the
integrity of these people, but those decisions were wrong. If benzene, a
radiomimetic, can have a PEL, why can't radiation? How did we decide that
we
should spend $1000 to avoid a man-rem (10 CFR 50, Appendix I; I've heard of
figures as high as $10000/man-rem.) when a significant fraction of our
population is denied access to basic health care?
I have probably benefited personally from these decisions. As a colleague
once
stated: "Radiations's been very very good to me!" Yet I am not happy about
it. It is ultimately demoralizing to devote your life to protecting people
from
imaginary hazards. This, not academic funding is the reason for the "Human
Capital Crisis in Radiation Safety" (HPS Position Statement, August, 2001.)
The opinions expressed are strictly mine.
It's not about dose, it's about trust.
Let's look at the real problem, for a change.
