Re: Mad Scientist stuff



Can we have some more information?  The question is "Which is more deadly,
a depleted uranium bullet or the radiation it emits?"  If the bullet is
still moving from being fired, then it is about one trillion (1E12) times
more dangerous than the radiation it emits.  Concerning its radiation, you
could probably put it in your pocket for 50 years, and never develop any
ill effects from it.  If it were laying on the ground, you would have
difficulty detecting it with most common radiation detectors from more than
6 ft.  If it were under a foot of soil, you what have trouble detecting it
with very sophisticated detectors, unless you were told where to look.  All
of this is another way to say that the radiation emissions from Depleted
Uranium are very weak.  The reason that there is still radioactive uranium
on the earth after 4.5 billion years, is that the half life is very long.
Long half life means low radioactive activity.

My own opinion.
