[ RadSafe ] Collective Dose

[Glenn R. Marshall]

I suspect, were we to add up all the statistical deaths from all hypothetical sources and hazards (not just deadly ionizing radiation) over the course of a year, the total would exceed the earth's population.  I do not intend to go to all the trouble to do that, but someone with a lot of spare time.....

There is nothing complicated about this issue. Collective dose is very 
meaningful if linear-no threshold theory (LNT) is valid -- it predicts 
the number of deaths caused. But if LNT is not valid, it is essentially 
meaningless except as a political tool.
