Abstract:
1. A method of electron beam processing bulk material solids comprising packing bulk material solids in a container having first and second opposed sides which define an internal container zone for irradiating the bulk material solids, forming a layer of the bulk material solids at a predetermined, substantially uniform solid thickness in the internal container zone, sealing the container to provide a controlled internal atmosphere within the internal container zone and with said sides in direct contact with the bulk material solids layer to form a block of bulk material solids, first passing the sealed container containing the block of bulk material solids through an electron beam radiation zone, and directly exposing the first side of the container to a first dose of electron-beam radiation which passes through the container first side to initially irradiate the block of bulk material solids in the container and, thereafter directly exposing the second side of the container to a second dose of electron-beam radiation which passes through the container second side to further irradiate the initially irradiated block of bulk material solids, whereby said first and second doses uniformly irradiate the bulk material solids.
