The paper presents the results of analysis of measurement methods for radon flux density from the soil surface. A new method of monitoring of undisturbed radon flux density from the soil surface is described. It may be applied within a wide range of meteorological conditions. The method is based on registration of a-radiation of radon decay products collected inside an accumulation chamber installed on the soil surface. The accumulative chamber has some small vent holes for partial soil gas emission. The procedure of calibration and determination of correction coefficients is described. The results of testing of the method and comparison of the monitoring data obtained by different methods are discussed. The new method differs from the analogues in the way that it allows the authors to investigate diurnal variations of radon flux density.

Key words: radon, flux density, undisturbed flux.
