Just for clarification, the activity associated with DU is primarily
associated with the U-238 which will account for about 80% of the total

Also remember that once the uranium is purified all of the progeny below
U-234 are effectively removed and will not return to secular equilibrium for
tens of thousands of years.

Would you forward this to Chuck.

DU is useful as a counter weight, so I wouldn't call it a waste product. The
activity in DU is mainly from U-234 with a half-life of 0.45 years and U-235
with a half-life of 0.71 billion years.

Thanks in advance

Feel free to contact Chuck Nicol and make him aware of the errors in his
analysis below which has been provided to members of the California State

Purpose  . DU is a chemically toxic, radioactive heavy metal waste
          product that has a half-life of 4.5 billion years, may cause
          genetic mutations, damage the kidneys and lungs, and may be
          cancerous when inhaled or ingested. Exposure to DU has been
          identified as a possible cause of Gulf War syndrome/illness.
          While the scientific understanding of DU's effect on health is
          still evolving, there appears to be ample evidence that there
          are some health risks associated with DU being embedded in the
          body.  As a result, this bill seeks to ensure that California
          veterans are notified of the availability of federally screening
          for DU exposure.
