C in air by the solid suspension method with liquid scintillation counter is presented. In this paper
conditions of the "Toluene-Triton X-100-Water" system as the solid suspension
methods of sample preparation and the effect of temperature etc.
are discussed. The preliminary results of determinations are also given.
