APPLICATION OF LIQUID SCINTILLATION METHOD FOR RADON DETERMINATION IN WATER

The paper presents the results of using the method of liquid scintillation counting (LSC) for measurement of radon concentration in water. The optimal settings of separation of alpha- and beta-radiation, as well as the efficiency of radon registration for different types of scintillators have been determined experimentally. The method was tested on water objects located on the territory of Semipalatinsk test site (STS). The comparison with gamma-spectrometric analysis was carried out for validation of the LSC method, which showed their good agreement. The obtained results allow recommending the LSC method for radioecological monitoring of water objects.
