Surface irradiation installation for eggs based on URT-0,5M accelerator

A surface irradiation installation based on the URT-0,5M accelerator (similar to 0.45 MeV, 1 kW) that includes built-in radiation protection and a radiation-resistant conveyor of products under the beam was developed. The oil-filled tank of the accelerator, where a circuit of high voltage pulse generation is located, has detachable side covers for easy of installation and maintenance. A vacuum diode is used for double-sided irradiation with a beam diameter of similar to 100 mm. The core of the pulse transformer is made of 1V-M magnetic conductors. Tests of the installation showed that the resulting doses of the electron beam are sufficient for surface disinfection of eggs (similar to 12 kGy) simultaneously on both sides at a rate of movement of egg cassettes of 3.1 cm/s, which provides a productivity of up to 5400 eggs/hour. Dosimetry showed that the designed protection provides the required level of safety.

Automated summary

A surface irradiation installation based on the URT-0,5M accelerator, with built-in radiation protection and a radiation-resistant conveyor, has been developed. The tests showed that this installation can effectively disinfect eggs on both sides, with a high productivity, and provides the required level of safety with its designed protection.
