[ RadSafe ] Genotoxicity of U

No. This is not good enough. You cannot ignore research articles because you dont like the person that cites them. This business of attacking me personally rather than addressing the science, which is in research which is not carried out by me is the pathetic refuge of those who cannot face up the the fact that they are wrong.

Except that the major proponent of this organization has discredited himself repeatedly.

There is sufficient evidence for all but the most intransigent ostrich here:

Hi Mike & Franz -

That is the 'Erzgebirge' (Ore Mountains) on the Czech-German border, and
geologists do call them the Erzgebirge in English.  These are Variscan-aged,
autometasomatic, two-mica granites that extend from France (through Germany,
Czech Republic, and Slovakia all the way into Ukraine and possibly beyond.
The uranium-enriched rocks of the Bohemian massif appear through windows -
Fensters - of eroded Alpine overthrust sheets in Austria in places such as
Obertauern, which happens to be a great place to ski!  The ore-forming
process creates solutions enriched in uranium and other metals at the
end-stage of crystallization.  These solutions are precipitated as zoned
intra- and peri-batholithic, contact metasomatic veins and veinlike zones,
if memory serves.

And you are very correct; a wasting disease (lung cancer) from very high
radon levels was an issue back in medieval times.  Uranium as a glaze on
ceramics and color for glass has been used for centuries.  Other metals such
as tin, bismuth & silver are associated with contact metasomatism in the
Erzgebirge.  Weathered Variscan granites also form intermontane sandstone
basins that host epigenetic uranium deposits such as at Stráz pod Ralskem in
Northern Bohemia.

I worked a bit more to the east in the Rozná area, Central Moravia, on a
project for the IAEA as well as at Stráz pod Ralskem.

Actually, one would expect it to have shown up in the miners in the Ore
Mountains, where the radon levels were high enough that the increase in
lung cancer was noticeable during medieval times.  Or in the pottery
workers who worked with uranium in glazes, in high concentrations and
conditions where contamination control wasn't even a concept.

	It seems to me that if uranium was a genotoxin its effects would

show up first in uranium miners and in uranium workers such as 
employees in gaseous diffusion plants.  (I am assuming that a 
genotoxin is a substance that would damage DNA and lead to birth
defects.)

	Has an excessive amount of birth defects been found --- even 
anecdotally --- in uranium miners or workers?
