Abstract
A radon exhalation monitor has been constructed and calibrated. The mo nitor is based on the adsorption of radon by active charcoal and the s ubsequent measurement of its gamma activity by means of high resolutio n gamma spectrometry. Exhalation rates may be determined with an accur acy of better than 20% within 48 h after exposure. The detection limit is estimated on the basis of counting statistics to about 0.1 mBq.m(- 2) s(-1).
