Effects of radiation dose rate, electron energy and oxygen on disinfection of sewage sludge cake were studied to obtain technological information on disinfection by radiation.Sludge films were irradiated with electron beams at different voltages and various dose rates in oxygen-containing and oxygen-free atmospheres. Without oxygen, the surviving fraction of bacteria decreased with increasing irradiation dose, but depended little on the sludge film thickness. No effects of dose rate and energy change were found in the ranges from 20 kGy/h to 65 MGy/h and from 0.5 to 2.0 MeV when the film was thin enough to allow electron beam penetration. Similar results were obtained with γ-ray irradiation. In the oxygen-containing atmosphere, higher disinfection efficiency was obtained with thinner films and lower dose rates.
