Comparison of radon measurements done by solid state nuclear track detectors and electronic devices in the framework of an EU-radon project

Abstract Radon measurements are performed within an EU-project in five European countries in selected houses and in the soil around the houses. The radon levels are measured with passive, solid state nuclear track detectors of the types LR 115, CR-39 and Makrofol and with active electronic devices. The active detectors are able to give time resolved data while the passive detectors give time integrated data. The measurements arediscussed in this report and some comparative data from different types of measurement are presented.
