Abstract The protective performance of medical diagnostic X-ray protective equipment is usually expressed with lead equivalent.According to IEC 61331-1, the measurement of attenuation performance of protective materials is mainly to study the lead equivalent of pure lead, lead-containing and lead-free materials under the conditions of narrow beam, wide beam and reverse wide beam in the range of 40~150kV X-ray. In order to study the shielding performance of protective materials under different measurement methods furtherly, it is necessary to establish the required X-ray reference radiation qualities and simulate or measure the corresponding energy spectrum.Based on the medium energy X-ray radiation device, by adding additional filter, eight X-ray reference radiations qualities in the range of 40～150kV are established and the maximum relative deviation of the HVL is 2.8%. The corresponding X-ray energy spectra are simulated by EGSnrc Monte Carlo simulation program, and the average energy are obtained. The results are consistent with the standard and the maximum relative deviation of average energy is less than 0.4% with IEC. The result can meet the requirements of lead equivalent measurement for X-ray protection materials.
