For measuring X-ray energy, the effective energy calculated from the half-value layer method has been used : In the case of continuous X-ray, however, the method based on the effective energy contains many errors. Therefore, the distribution of the energy of the primary X-ray was measured using the scintillation spectrometer. The method of the measurement and the results of that were investigated, too.
