[ RadSafe ] pyrophoric uranium considered nonessential

[John R Johnson]

James et al

But the energy of the impact raises the temperature to a temperature that
results in the DU to be insoluble in the lung (is ICRP Type W and or Y).

When finely divided, as uranium is when a speeding uranium bullet hits
a hard target, uranium ignites spontaneously in air at room temperature.

When uranium ignites in air, it produces uranyl oxide (UO3) which
is a reproductive poison and a developmental poison.  Poison
weapons are illegal.  Weapons which continue to act after a battle
are illegal.  Weapons which act off the battlefield are illegal.

Sincerely,
