This paper presents a survey of irradiation treatment of sewage sludge in the world. Since the first sludge irradiation plant was built in Geiselbullach, West Germany in 1973 which used ⁶⁰Co as irradiation source, many sludge irradiators were constructed in USA, India, Japan, Canada, Poland and so on, which used ⁶⁰Co, ¹³⁷Cs or electron beam as irradiation sources. Some basic researches on irradiation treatment of sewage sludge are, respectively, reviewed, including optimization of irradiation parameters, synergistic effect of radiation with heat, oxygenation, irradiation-composting and potential applications of treated sludge. Some proposals have been suggested for further development of this technology.
