Abstract
A novel technique and apparatus for shielding electron beam and similar product irradiation zones with a separable shielding housing extending transversely of the longitudinal line of product flow and slidably openable in a transverse direction orthogonal to both the electron beam and the direction of product flow, both in passing the beam and along the line, resulting in substantial space saving, more facile accelerating to the irradiation and product feed zone and less costly and sizeable shielding apparatus.
