Abstract

Abstract: 109 Cd is quite a useful nuclide for the calibration of X-ray spectroscopy, gamma-ray spectroscopy or as an excitation source in X-ray fluorescence. In this work, 4π(PC)e-X coincidence counting and 4π(LS)ce counting were used to determine the activity of the 109 Cd solution. The two methods showed good agreement in their counting results. On the other hand, the mean value came from the results of the two methods was used to calibrate the well type ionization chambers to maintain the radioactivity measurement standard of 109 Cd at INER. Highlights: 4πe-x coincidence and 4π(LS)ce methods were used. Gaussian peaks were chosen to fit the spectrum measured by the 4π(LS)ce method. The two methods showed good consistence in their counting results. The weighted mean was used to calibrate the three well type ionization chambers.
