title: Application of the sum-peak method to activity standardizations of extended 60Co sources.
abstract: The sum-peak method was successfully applied to the determination of the activity of extended (60)Co sources measured on a HPGe detector. Monte Carlo simulations were used to account for the effects of the spatial variation of the efficiency across the sample volume and for the angular correlations between the emitted gamma rays. The determined activities agree with the reference values within a range of 1.0%.
