It's also useful for fishing, as you don't have to use those highly
toxic lead weights.

The U-235 contribution to the total radioactivity is always trivial,
regardless of enrichment.

In DU, most of the radioactivity is from U-238.  In U-nat, it's 49% each
from U-234 and U-238 (balance from U-235).  In highly enriched U, nearly
all the radioactivity is from U-234.

Would you forward this to Chuck.

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

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
          for DU exposure.
