Beta Rays

 Products to be ionized using beta rays (accelerated electron beams) are exposed at controlled speed to the beta radiation. The beta rays are generated from an electron beam machine. The emitted electrons have one energy level: 9.8 Mev +/- 0.2. An automatic system of conveyors moves the products into irradiation cell, where they are passed under the electron beam according to the specified speed. The speed depends on the dose level and nature of the product. The treatment is generally carried out in two passes under the beam: the product, typically in its cardboard box passes by the electron beam, following witch it is inverted and the opposite side of the cardboard box is treated, in what is know as double-side treatment.
