So,  inhaling 5 grams of depleted uranium trioxide, or about
20 times the  LD50/30 for rabbits, results in only a 182 mrem
exposure, according to the  calculator, without any mention
at all of the chemical  toxicity.
James you might want to check your math.  I might work in these  new fangled 
units of mSv and have never had to use rem in my work, but I always  thought 
that 182 mSv was actually 18.2 rem.  please let me know if I'm  wrong :-)
 
 



And people can't understand why I don't think it's such  a
great idea to "merely" have radiation safety professionals
in charge  of exposure decisions for heavy metals.
Hmmm, again I must have missed something over the years I always thought  
that WISE was a watchdog (always sound much nicer than anti-nuclear)  
organisation that had spent a lot of time and effort to convince people that  Nuclear 
energy was bad for people and the environment and people, including  everything 
to do with the Uranium fuel cycle and the use of depleted  uranium.  Maybe 
they've seen the light and all become radiation safety  professionals and have 
decided to downplay the risks of exposure to depleted  uranium and all of the 
other by-products of nuclear energy :-)
 
I don't know what their friends in the NIRS would say about that - see  below 
for links to the WISE site on Uranium and the NIRS home page which appears  
proud to highlight their links with WISE (World Information Service on  Energy)

If I'm mistaken about any of the above James please let me know.
