Radiation technology may contribute to the environmental protection to a great extent. Electron beam
industrial installations for flue gases containing SOx and NOx treatment have been
already built in China and Poland. The same technology for high sulphur and high humidity off-gases
(low quality lignite) has been successfully tested in an industrial pilot plant in Bulgaria.
Pilot plant tests performed in Japan have illustrated that by applying electron beam for municipal
waste incinerator off-gases treatment the concentration of dioxins can be reduced by 80%,
other persistent organic pollutants can be depredated as well. The positive results of electron beam
wastewater treatment are the basis for a full-scale industrial plant being built in the South Korea.
A pilot gamma plant for sludge irradiation producing a high grade organic fertilizer is in operation
in India. All these achievements are reported in this paper.
