AW: [ RadSafe ] Radon from DU

I fully support your comment, which shows a good understanding of the decay
chains! If DU would be disposed of it would take a few thousand years to get
radon-226 into equilibrium (look at the half lives!) Who would care for Rn
222 at this time, taking into account the ubiquitous effects of Rn-222? 

I hope that my progeny (!!!) then will have found a solution or hopefully
have agreed on that these riska are negligible. 

Best regards,

Betreff: [ RadSafe ] Radon from DU

 One major fact that has been overlooked in the ongoing debate about radon
from DU is that the radon emanating fraction (radon that actually leaves the
host matrix) is probably several orders of magnitude LESS than that from
uranium tailing sands.  If the DU is disposed of in metallic form (perhaps
ingots) the perceived problem of radon from DU disposal will likely be moot.
If true, this would make a very small risk an infinitesimally small risk.
