Abstract: The KFA took part on a wide-ranging survey of indoor radon measurements in the Federal Republic of Germany. The measurementswere carried out in 150 households during four periods from January 1981 til April 1982. Differences were found between the radonconcentrations in living rooms and sleeping rooms, during winter time and summer time and between isolation glass windows and common windows due to energy conservation efforts. It appeared that the ventilation rate is one of the dominant factors. The radonconcentrations are lower than expected. The radiation dose caused by inhalation of the radon are calculated from the measurements to be 180 mrem per year for the lungs or an effective dose equivalent of about 0,22 mSv per year.
