Publikováno v: 2020 21st International Scientific Conference on Electric Power Engineering (EPE).

Four Monte-Carlo codes where tested to simulate bremsstrahlung spectra for accelerated electron beams at the energy range 4–20 MeV. All four codes give the same shape of the spectrum, in which in addition to the bremsstrahlung part there are charac

Publikováno v: 2018 19th International Scientific Conference on Electric Power Engineering (EPE).

The effect of irradiation by gamma quanta of a substance is caused by the absorbed dose. But in the experiment, it is possible to measure the exposure dose. The analysis of the results of sample iirradiation on electron accelerators is complicated by
