In the last decade the radon isuue has become one of the major problems of radiation protection. Animal studies as well as epidemological studies showed an increades lung cancer risk. A new personal radon-dosemeter on the basis of a CR-39 ( polyallyl digycol carbonate) track-etch detector has been developed. The read-out of the detector is based on the image-processing technique. The actual efficiency of the new dosemeter, obtained with semi-automatic personal-computer based image-analysis system, is 1.43 +- 0.15 tracks/cm²/(kBq/m³h), which is about three times that of the widely used Karlsruhe-type detector based on polycarbonate detectors.
