Abstract The analysis and comparison of the geometric parameters, the correction factors and the method to determine the correct factor of 137Cs air kerma primary standard which participated the 137Cs air kerma key comparison BIPM RI (I)-K5,organized by International Bureau of Weights and Measures (BIPM) , will provide useful reference about the design in ionization chamber, the measurement of correction factors and the method of simulation for our national primary standard of air kerma for 137Cs gamma-rays.
