       Thanks for this.


       Might you have time to look for a way to work this into the 
Wikipedia article on uranium?  I couldn't find this mentioned, and it 
looks like it belongs, either in the section on " Human exposure" or 
"Effects and precautions".  I don't want to take the lead on this, but 
I'd be pleased to help with the syntax of the Mediawiki markup language 
if you'd like.
