	Unknown energy of electron beam of linear accelerator was estimated by photo activation of only one activation detector - foil of natural indium. Three different photonuclear reactions were considered: 115In(gamma, gamma')115mIn, 115In(gamma, n)114mIn and 115In(gamma, 2n)113mIn. Ratio of saturation activities R(113mIn)/R(115mIn) and R(114mIn)/R(115mIn) were determined by standard gamma spectroscopy in electron energy region of interest (10 MeV - 23 MeV) using indium foils exposed in the FLNR microton MT25 bremsstrahlung beam. The choice of cyclic accelerator MT25, as a reference machine, was made due to the fact, that the energy of its electrons is known with accuracy not worse than 1%. Same ratios of saturation activities were determined after exposition of In activation detectors in photon beam of linear accelerator. The fact that both irradiations, by microton MT25 and accelerator, were performed in identical geometry using same target (3 mm of Tungsten) allowed us to estimate electron energy of accelerator by comparison of ratios of saturation activities obtained by both machines. Small variation in accelerator electron current was taken in consideration.

Unknown energy of electron beam of linear accelerator was estimated by photo activation of only one activation detector - foil of natural indium. Three different photonuclear reactions were considered: 115In(gamma, gamma')115mIn, 115In(gamma, n)114mIn and 115In(gamma, 2n)113mIn. Ratio of saturation activities R(113mIn)/R(115mIn) and R(114mIn)/R(115mIn) were determined by standard gamma spectroscopy in electron energy region of interest (10 MeV - 23 MeV) using indium foils exposed in the FLNR microton MT25 bremsstrahlung beam. The choice of cyclic accelerator MT25, as a reference machine, was made due to the fact, that the energy of its electrons is known with accuracy not worse than 1%. Same ratios of saturation activities were determined after exposition of In activation detectors in photon beam of linear accelerator. The fact that both irradiations, by microton MT25 and accelerator, were performed in identical geometry using same target (3 mm of Tungsten) allowed us to estimate electron energy of accelerator by comparison of ratios of saturation activities obtained by both machines. Small variation in accelerator electron current was taken in consideration.
