Abstract

The device shall be used for the prevention of the release ofX-ray of -rays through an aperture in a screening channel, forexample produced in irradiation with an electron beam. It includesa screening wall (2) forming a screened channel (3) with inlet andoutlet hole. A source (1) generating X-ray or -rays is fitted inwall (2). Multiple partition walls (7-1, 7-2 & 7-3) are fitted inchannel (3) and are folded at least once between its inlet andoutlet hole.9 claims, 15 figures
