Abstract: The invention pertains to the area of radiation production process, specifically to the technology of radiation modification of organic materials and may be used for the creation of production lines for the manufacture of radiation-modified polymer films.The method of irradiating polymer films by an electron beam comprises a two-stage application of an accelerated electron beam on sections of moving polymer film until the preset radiation dose has been absorbed. The duration of the set time interval between the end of treatment Stage one and the beginning of treatment Stage two of the initially irradiated film section is no less than 500 msec. The set dose accumulated by each section of the film in Stage one is sufficient to alter the polymer film material from a free molecular state to a cross-linked state characterized by the formation of 3-dimensional molecular structures having a greater molecular mass.

Abstract: A radiation sterilization conveyor unit for sterilizing biological products, prolonging shelf life of food stuff, decontamination of clinical waste and decontamination of microbiological products. A power unit, modulator, and an ultra-high frequency generator are connected via microwave waveguide elements to an electron injector, accelerator and beam scanning system. The injector, accelerator and beam scanning system are located in shielding made of cast iron or lead. A disk-shaped transporter is provided and extends in part in a cavity in the shielding. Products to be irradiated are placed on the disk-shaped transporter and the transporter is selectively rotated for placing the products in the field of accelerated electrons. The shielding and transporter block dangerous levels of ionizing radiation.
