<p>METHOD OF AND APPARATUS FOR SHIELDING INERT ZONE ELECTRON IRRADIATION OF MOVING WEB MATERIALS This disclosure is concerned with novel techniques for shielding electron-produced scattered radiation in systems wherein a web or sheet is passed longitudinally through an electron irradation processing region or zone, through the use of a shielded enclosure comprising longitudinally extending shielded-wall collimator slots operating in conjunction with cavity shield traps and critical angles of web-guiding inlet and outlet feed that insure minimal irradiation escape while providing a minimal volume for oxygen-limiting in the irradiation processing zone.</p> |
