Re: Ra, 25 mrem/y



In order to respond to this hypothetical, it needs to be more clearly
defined.  Answers to the questions below are only the minimum that must be
considered.  As they are explored additional questions will be identified.
However, at some point we may have enough information to scope the problem.
1.  How long would this walk down a country road  or walk through a city be?
2. How should the risk information be provided?
3. How precise should the risk information be?
4. Should all people faced with a similar risk be provided with similar
information?
5. What about the possibility that the exposure is not a risk but a benefit?
6.  How do we provide information on the alternative risk created by
ameliorating a specific risk that we remove?
7. What if removing a risk for me increases a risk for someone else?
8.Should we always be provided with information on every risk that we are
exposed to each time we are exposed to it?
9. How should we be informed of variations in risks to which we are exposed?
10.  Should this notification be provided even when we are involved in an
activity that we might not lie to be disturbed at?
