I once saw 2 maps of the US, one of background radiation levels, and
one of cancer incidence. The correlation was very strong, but it was
the exact opposite of what LNT suggests, ie the higher background
areas had the lowest cancer rates. Unfortunately I can't remember the
source of the maps.


NT

Confirmed, but can't provide a link. The cancer deaths also correlate
pretty well with population density, suggesting it could well be urban
pollution.

There have also been studies that suggest the apparent cancer clusters
round nuclear and oil installations are due to the number of incomers,
which could also apply in cities, though no mechanism for the
correlation was suggested. It may, of course, just be better reporting
as people are checked by doctors when they move into an area.

Low rates in areas of high natural radioactivity could be linked to a
lack of population movement, as most of them (in the UK, at least) are
pretty isolated with stable populations.
