AB  - In this study, gamma spectrometric efficiency measurement uncertainty of137Cs in vegetation sample is investigated. Each uncertaintycomponent is evaluated and quantified. For this purpose, n-type 70% efficiencyHPGe detector was used. The combined standard uncertainty of 137Csefficiency was found to be 2.43%.
