  Abstract:  The International Intercomparison Measurement of Soil-gas Radon Concentration, of Radon Exhalation Rate from Building Materials and of Radon Exhalation Rate from the Ground Surface was held in Pribram, Czech Republic in September 2002. It was attended by participants representing 10 different institutions from 8 countries - France, Germany, Hungary, Poland, Romania, Spain, United Kingdom and Czech Republic. A test site for the intercomparison of soil-gas radon concentration and of radon exhalation from the ground was located in the field, at an area characterized by a high soil permeability and by relatively high values of soil-gas radon concentration. A concrete block made from a slag with a high content of radium was used for the intercomparison of radon exhalation rate from building materials. As for the soil-gas radon concentration and the radon exhalation from the concrete block, a relatively good agreement was observed. The intercomparison differences expressed as a ratio of the standard deviation to the arithmetic mean were about 26 - 28 percent. Substantially larger differences were observed during measurements of radon exhalation rate from the ground surface. The value of the ratio SD/mean was 0.72.
