John was correct: The first two matches when I Googled
for "Uranium on Amazon" were small quantities sold for
research purpose and testing Geiger counters (<a

The second was is labeled 766 cpm (counts per minute). If I
computed correctly, to get this many cpm, this container would
have roughly 30 micrograms. (For my calculations, see <a

If I understand correctly, the primary problem with
uranium is NOT radioactivity but toxicity, roughly like eating
or inhaling lead. See Wikipedia, "Uranium" (<a

It is all in context, Spencer. Doctoral research by Stephanie
Raymond-Whish at N. Ariz. Univ. established that Uranium is also
an estrogen mimic. That accounts for the rapid rise in cancer
rates among Navajo women when the US started to mine on the Navajo
Reservation, including at least 2 members of Raymond-Whish's
family including her mother. <a moz-do-not-send="true"

Thanks for this. <br>

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. <br>

I think that all members of Congress who vote for extended uses
of uranium should be wiling to have the female members of their
families drink groundwater from down slope of the old mining sites
tailing ponds and slag piles. <br>
