A radon exhalation monitor has been constructed and calibrated. The monitor is based on the absorption of radon by active charcoal and subsequent measurements of its gamma activity by means of high resolution gamma spectrometry. Exhalation rates may be determined with an accurancy of better than 20% within 48 h after exposure. The detection is estimated on the bais of counting statistics to about 0.1 mBq.m-2s-1.
