Abstract
A stray radiation grid for penetrating radiation is produced by starting with a carrier material and producing holes in a first surface thereof, and subsequently filling the holes with penetrating radiation absorbing material. A second, opposite surface of the carrier block is etched away to reduce the thickness of the carrier block, leaving a carrier which is flexible and bendable, from which the radiation absorbing material projects as a number of free-standing absorption elements.
