- Abstract:
- The efficiency of a 226Ra aqueous solution source in the radium-radon secular equilibrium against the gamma reference ionization chamber in KRISS has been obtained both by calculating from the photon energy-dependent efficiency curve of the ionization chamber and by measuring with an 226Ra standard source. The two results of calculation and measurement have showed such a good agreement that the gamma reference ionization chamber may be used to certificate the radioactivity of 226Ra aqueous solutions in the secular equilibrium and its traceability could be linked to the multi-radionuclide calibration of the ionization chamber.
