Radiation technology for cleaning of air pollution


IAEA supported project in Poland employs a radiation technology – electron beam accelerator facility to treat flue gases from coal-driven power plants, thus reducing the emissions of sulphur dioxide, nitrogen oxides and polycyclic aromatic hydrocarbons, which can cause damage human health and the environment. Acid rains in and around the site are the result of the acidic pollutants.   

The technology is useful in countries which produce electricity by coal/oil combustion and required to meet pollution control regulations. Unlike other conventional technologies, the use of electron beam accelerator technology removes 95% of sulphur dioxide, and 70% of nitrogen oxides present in flue gases. The by-product is high quality fertilizer for use in agriculture. Not much of secondary waste! 
It is a proven green technology according to the Director General of the Institute of Nuclear Chemistry and Technology, Poland (source: www.iaea.org)
