Destruction of Ascaris ova by accelerated electron

Abstract

We investigated the efficiency of radiation treatment to destroy Ascaris ova viability and found that no ova were viable after exposure to 0.75 kGy (D90 at 0.39 kGy). Although the outer coat of the Ascaris ovum had a protective effect at low doses (0.20 kGy) no difference in ova viability was observed at 0.30 kGy. As the doses commonly used for sanitary treatment of wastewater are much higher, Ascaris ova should be effectively eliminated from sludge by the 10 kGy dose required by EPA regulations (U.S. EPA, 1993 Federal Register 58, 9248–9415).
