Abstract: Since 1984 in a German-Turkish project on earthquake prediction research has been operating the North Anatolian Fault Zone in Turkey. Among many other parameters changes in radon emission are investigated. Plastic nuclear track detectors (Kodak cellulose nitrate LR 115) are used to record alpha-particles emitted from radon and thorn atoms and their daughter isotopes. At regular intervals of 3 weeks the detectors are replaced and analysed. Thus a quasi-continuous time sequence of the radon soil gas emission is recorded. The authors present a comparison between measurements made with electronic countermand with plastic track detectors
