The granted patent (Publication Number: US11850315B2) discloses a combination of a device and a flexible bag designed for sterilization purposes. The device includes a first accelerator emitting an electron beam with energies between 400-500 keV and a second accelerator emitting an electron beam with an energy of at least 4 MeV. The sterilization zone is defined as the space between the first and second accelerators and the flexible bag, ensuring the bag is within the electron beams. The arrangement involves the accelerators being horizontally adjacent to each other and vertically adjacent to the flexible bag, with a distance between them ranging from 1.5 cm to 7 cm.
Furthermore, the patent details the specific configurations of the accelerators, with the second accelerator emitting electron beams within the range of 4-5 MeV. The device is positioned in a radiation-proof area with containment measures such as walls and floors at least 65-cm thick, made of lead, to prevent the escape of radiation emitted by the electron accelerators. This setup ensures the safe and effective sterilization of the flexible bag while minimizing radiation exposure to surrounding areas, highlighting the importance of safety measures in such processes.
