The characteristics of radiation were investigated for a prototype X-ray free electron laser machine with 250-MeV electrons and 49-nm-wavelength light. The doses both inside and outside the shield tunnel including the maze were measured in relation to the electron beam losses and were compared with the empirical formula and Monte Carlo simulations.
