چکیده انگلیسی
Seven methods of radioactivity measurement were used to standardise an 125I solution within the frame of an international key comparison organised by BIPM: photon-photon coincidence counting with two NaI detectors, photon sum-peak counting in a NaI well detector and in a 4Ï CsI(Tl) sandwich spectrometer, total emission counting in a windowless 4Ï CsI(Tl) sandwich spectrometer, electron-X,γ coincidence counting and electron-X,γ sum counting in a pressurised proportional counter inside a NaI well detector and liquid scintillation counting with the CIEMAT/NIST method. The solid sources were prepared by quantitative drop deposition with addition of AgNO3. The measurement methods, the results and the applied corrections are described and discussed.
