The paper presents the results from a primary standardization of (137)Cs using two independent methods - efficiency tracing using PC-NaI coincidence and the TDCR method. The nuclides (60)Co and (134)Cs were used as the tracers. Primary standardization of the (134)Cs is also discussed. The efficiency extrapolation was carried out by measuring samples of varying mass and using the wet extrapolation method. The results obtained are in good agreement; the differences did not exceed 0.5%. The advantages, pitfalls and also possibilities for improvement of the procedures are discussed.
