Re: DU in Iraq

["Bjorn Cedervall" <bcradsafers@HOTMAIL.COM>]

I went over my own first calculations and couldn't find any error so

we are back to about 0.6 million tons of uranium. Thanks for your

collaboration. I apologize for a couple of typo(e?)s in my first message.



75/600 000 is approx. the ratio of interest (about 0.01 %).

PS. I am glad that I didn't have to do that one with pounds, square

miles and cubic inches (or feet?).

I believe you are out by a factor of 10.



432,162 sq.km = 432,162 x 1e+10 sq.cm = 4.32e+15 sq.cm.....

4.32e+15 sq.cm x 1 m (=100 cm) = 4.32e+17 cubic cm

NOT  4.32e+18



Thus your final estimate of 5.1e6 metric tons in the top 30 cm becomes

0.5e6, similar to Bjorn's 0.6e6

Hi Peter:

Thanks for catching my late night math error. Thus my estimate based on 2.5 

ppm U

crustal average and Bjorn's "English Garden" average U come into "agreement" 

for

total U in Iraq's top 30 cm.
