Radiation shield using electrical insulating materials and the spacecharge fields therein

摘要

The invention provides improved shielding from high energy radiation, especially radiation in the form of electrons with kinetic energy from 0.1 to 10 million electron volts. The improvement is produced by the build-up of an electric field in the insulating material which acts to further attenuate or deflect the penetration of such radiation. The electric field builds up in the insulator and surrounding media because of the stopping of charge stemming from prior impinging radiation.
