The destroying effect of ionizing radiation on parasitic resistant stages in sludge has been tested. Suitable for that process is an electron beam accelerator which will be provided with energy from the electric power supply network which can be switched on and off according to the requirements. Such modern utilities have an enormous beam capacity and a high operating safety. The process is working according to the continuous flow principle and at room temperature. In a series of 13 experiments the effect of different doses has been tested. A dose of 480 kRad (accelerating voltage; 400 kV, beam current; 10 mA, irradiation time: 24 sec.) can easely obtained in practical work and is economically acceptable. By these means approximately 97% of the following parasitic stages have been destroyed: undeveloped eggs of Ascaris suum, Trichuris suis, Fasciola hepatica and gastrointestinal strongylids of pigs, embryonated eggs of Capillaria obsignata and probably of Taenia spec. A few third-stage larvae of Oesophagostomum (Strongylidae) of pigs survived even 108 sec of irradiation; however, they did not develop to maturity in the definitive host. Approximately 25% of the sporulated oocysts of Eimeria renella were still infective after 108 sec of irradiation.
已对电离辐射对污泥中寄生虫抗性阶段的破坏作用进行了测试。适用于该过程的是一种电子束加速器，它将由可根据需要开关的电网提供能量。这种现代化设备具有巨大的束流容量和高度的操作安全性。该过程按照连续流动原理在室温下进行。在一系列13次实验中测试了不同剂量的效果。在实际工作中可以轻松获得480千拉德的剂量（加速电压；400千伏，束流；10毫安，照射时间：24秒），并且在经济上是可以接受的。通过这些方法，以下寄生虫阶段约97%已被破坏：猪蛔虫、猪鞭虫、肝片吸虫和猪胃肠道圆线虫的未发育卵、毛细线虫和可能的带绦虫属的胚胎化卵。猪食道口线虫（圆线虫科）的一些三期幼虫甚至在照射108秒后仍存活；然而，它们在终末宿主体内并未发育成熟。雷氏艾美耳球虫的约25%的孢子化卵囊在照射108秒后仍具有感染性。
