Summary

This work presents the methodology used for the setup of the dosimetric standard at the Laboratoire National Henri Becquerel (LNHB) for the continuous X-rays irradiation field of medium-energies (100 kV to 250 kV) in term of air-kerma rate. Principle of measurements and characteristics of the standard are described. Additionally, a first assessment of global uncertainty budget on the value of air-kerma rate taking into account several correction factors and a first estimate of that of a calibration are developed.
