Re: DU in Iraq

>Have you made any progress on Otto's question about calculating the amount

of naturally occurring uranium in Iraq?



---

Here is an estimate of the magnitude - please double check, critisize or 

correct

if necessary (I am doing the calculation directly on the sqreen as I am 

typing this):



Area of Iraq: 434,925 km2 = approx 4.34 E11 m2.



Amount of uranium and thorium in a "typical English garden" taken from my

memory of the video film by and with Lord Marshall some 15 years ago:

8 kg - I am uncertain about the relative parts but it may be 2 kg U + 6 kg 

Th.

The garden was given for a depth of 1 m and an area of 10 m x 40 m.



For a depth of 0,3 m this gives us an "area density" of

2,4 kg/400 m2 = 0,6 kg/100 m2 = 0,006 kg/m2.



Assume the same percentage of U and Th for Iraq as for England (I have no 

idea

whether this is reasonable - can any geologist or just well read Radsafer 

comment?)



Finally: 4.34 E11 x 6 E-3 = 2.6 E9 kg = 2.6 E6 tons.



Now if 25 % of that is uranium we would land somewhere around 0,6 E6 tons.



My personal initiative only,
