The article considers the change in the average energy of photon radiation with the upper limit of the spectrum of 6 MeV, generated by a medical linear electron accelerator (or LINAC for short), when radiation passes through a lead filter of various thicknesses. The calculation of the spectrum and average energy of photon radiation is carried out using Monte Carlo modelling. Additionally, the coefficients of attenuation of photon radiation by a lead filter are calculated. Particular attention is paid to the influence of the filter on the shape of the spectrum. The validation of the calculation is determined by comparing the model and experimentally obtained attenuation coefficients for kerma.
