Abstract
The activity concentrations of natural radionuclides in sands, gravels, cements and in different kinds of concretes were measured by γ-spectrometric methods. The222Rn exhalation rate from concretes was measured by closed chamber method and the emanation coefficient was calculated. Both used methods are described in detail and obtained results are discussed from point of view of allowed hygienic limits.
