Abstract

Collimator is partic for producing parallel beams of X-rays, alpha-, beta- or gamma-radiation for subsequent measurement purposes, consisting of a cylindrical support member, within which are sheets of material with a high coefficient of absorption for the radiation being used, wound round a central tubular passage, either in the form of concentric coaxial cylinders or in a spiral.
