1. A combination of a device and a flexible bag to be sterilized, the device configured for sterilization of the flexible bag, comprising:
the flexible bag;
a first accelerator that emits an electron beam with energies between 400-500 keV;
a second accelerator that emits an electron beam with an energy of at least 4 MeV;
a sterilization zone, wherein the sterilization zone represents a space formed between the first and second accelerators and the flexible bag to be sterilized, such that the sterilization zone is within the electron beams emitted by the first and second accelerators;
wherein the first and second accelerators are located horizontally adjacent to each other, wherein the first and second accelerators and the flexible bag to be sterilized are located vertically adjacent to each other, and
wherein a distance between the flexible bag to be sterilized and the first and second accelerators is between 1.5 cm and 7 cm.
