Abstract

A collimation device for an irradiation apparatus comprising in particular a radioactive source having a generally flat shape constituted by a source-holder frame in which radioactive elements are disposed in spaced relation, characterized in that it comprises a mask having open portions which is placed in parallel relation in front of at least one face of said source and in proximity thereto, said mask being made up of a series of screens formed of absorbent material and adapted to project in the direction of packages to be irradiated which pass in front of said source, each screen having a transverse cross-section which decreases from said source towards said packages.
