Re: Radon's linear dependency

I agree entirely with Ruth's position, except I think 'collective dose' should also go in the bin, especially when the reason for reporting it is to give a handle on risk assessment (even if the next step of mulitplying by 0.0005 is dropped).  Individuals get cancer, so the only information of any interest is how much dose any individual may have been exposed to.  Therefore, rather than collective dose, a median dose should be reported, along with a worst-case dose.  And time intervals should also be included: i.e. reported as dose per annum, so it's clear getting 5mSv each year for a decade is not the same as a 50mSv dose.

The problem, as I see it, is that in making and enforcing regulations, the federal agencies apply a simple (and simple-minded) linear conversion factor 

to "convert" dose (any kind: collective, average individual, external, CEDE) 

to "latent cancer fatalities" ..... 



 It is not even a question of 

"disproving" the LNT, but of convincing, or forcing, or whatever, the 

regulatory agencies not to publish this kind of simplistic stuff.  Should we not try to convince DOE, EPA, NRC to just publish collective doses?
