Protection Against Penetrating Radiation. The external dose at the surface of 1 kg of pure plutonium (neatly pure Pu) obtaiaed from uranium irradiated at 3000 MWd/t is ca 0.025 Gy/h (2.5 rad/h) (23). Thus, for the direct handling of kdogram quantities of Pu, lead-lined gloves (Rad-Bar) are recommended. Isotopes other than Pu, which are present ia normal Pu, emit weak y- and x-rays for large amounts of these isotopes lead shielding is necessary. In plutonium compounds with light elements, especially fluorides, the (n, n) reaction produces significant neutron doses which requite shielding to slow the neutrons to thermal energies and absorb them.  [c.204]
