Abstract
<PICT:0839874/III/1> Organic or inorganic materials are exposed to radiation and simultaneously submitted to an electric field, one or both of which are pulsed. Radiation may be alpha, beta, or gamma radiations, X-rays, protons, or neutrons, but is preferably high speed electrons concentrated into a beam by a magnetic field. It is stated that the effect of pulsation and the electric field distributes the energy of the electron beam, and enhances the effect of secondary emission. A suitable apparatus comprises a high voltage accelerator 10 from which pulses of electrons pass down tubes 12 and 13 where they are focused by a magnet 17 and emerge from the conical member 15 through a stainless steel or beryllium window 16 to a substance 20 mounted on a grounded base 21 and covered by aluminium foil 22. An electric field is generated by a unit 23, which may also be pulsed. The pulse energy source may supply both requirements and be controlled independently. Substances treated include resins, rubber, silicones, and polymers, e.g. polythene to promote cross-linking and foodstuffs for killing bacteria.
