Irradiation system with compact shield

摘要

An irradiation system includes a radiation source providing radiation in a localized radiation exposure area and a shielding structure around the radiation source. A conveyance system transports product into the shielding structure, through the radiation exposure region and out of the shielding structure. The conveyance system includes an input portion for carrying the product into the shielding structure at a first elevation. A first elevator moves the product from the first elevation to a second elevation different from the first elevation. A processing portion of the conveyance system carries the product at the second elevation through the radiation exposure region. A second elevator moves the product from the second elevation to a third elevation different from the second elevation. An output portion of the conveyance system carries the product out of the shielding structure at the third elevation.
