The most objective assessment of radon hazard of build-up area can be the amount of radon released from the underlying rocks. In the Russian Federation, the criterion of radon hazard is the radon flux density, measured by the method of accumulation chambers. The paper presents the results of measurements obtained by the method of accumulation chamber using two measuring complexes and the method of "two depths". The measurements were performed on a testing site of Tomsk (Russia); the type of soil is loam. Studies have shown that the considered assessment methods of radon risk have significant drawbacks, because they do not allow reliable determination of the amount of radon coming from the soil surface.
