Several kinds of common X-ray energy spectrum measurement technology in the radiation simulation accelerator radiation field are reviewed. The basic principle, the classic system composition of measuring equipment, major parameter characteristic, recent progress, applicability, merits and weakness are expounded. The developments and the characteristics of seveval common spectral unfolded methods are summarized by taken the absorptive method as an example. Then, the progress in the measurement of pulsed X-ray energy spectrum in Northwest Institute of Nuclear Technology is introduced in detail. In addition, the noise-immune and scattering control technology in the energy spectrum measurement system are commented. Furthermore, according to the present conditions and technology readiness level, the perspective of future development of this work is discussed.
