2.3 Gamma spectrometry
Activity concentrations of 226Ra at 186.2 keV (3.5 %) and 133Ba at 302.8 (18 %) and 356 (62 %)
keV in the solid and solution samples were determined using N-Type HPGe detector (Bruker
Company, with relative efficiency of 60 % and FWHM of 0.89 and 2.0 keV at 122 and 1332.5
keV, respectively).
