Re: Collective dose and its monetary valuation

[Jean-Michel Mure <Jean-Michel.Mure@andra.fr>]

Mr Bill Clipton,


I think you're missing the point. The monetary valuation of collective dose
is not meant to be used in the way that you are trying to suggest it. I am
totally aware of the fact that this is a concept which must be dealt with
very carefully because it refers to the value of human life.
I guess you have heard of ALARA principle and its implications.
Would you be ready to spend the same amount of money to prevent a 1 Sv
exposure and a 1mSv exposure ?
The answer is not so obvious and you need to consider the amount of exposed
people, the cost of reducing exposure and other concepts such as  risk
aversion. Furthermore, there is an inverse proportionnality relationship
between the cost of radiation protection and the risk of exposure. In other
words, a small amount of money can be used to reduce high doses but it
becomes very expensive and difficult to reduce very low exposures.

So how do you deal with all these problems and concepts ? One solution is to
introduce a monetary valuation of collective dose in the optimization
process which can help the decision maker to use available resources in such
a way that it produces the highest benefit to the group of people (workers,
public ...) while making sure doses are kept as low as reasonably achievable
(See ICRP 22, 37). This is the basis of cost-benefit analysis.

My interest lies in the fact that this valuation is not universal (it may
depend on the standard of living), that is can be different depending on
which groups of people you are dealing with (children, adults, patients,
radiation workers ....) and BY NO MEANS  in setting up any liability for a
concept which is, by the way, widely and universally  used across the field
of radiation protection.

All my regards,

Jean-Michel Mure
