Abstract: The present disclosure proposes a security inspection equipment and a radiation detection method, and relates to the field of security inspection. The security inspection equipment according to the present disclosure comprises: a ray emitter; and a radiation detector comprising a forescatter detector, the forescatter detector and the ray emitter located on opposite sides of an object to be detected; wherein the radiation detector further comprises at least one of the following detectors: a backscatter detector located between the ray emitter and the object to be detected; or a transmission detector wherein the transmission detector and the ray emitter located on opposite sides of an object to be detected. Such a security inspection equipment has a forescatter detector, which can be used in combination with backscatter detector, to reduce detection dead angles, and thus the detection of the internal information on the opposite side of the ray source can be optimized; the forescatter detector can be used in combination with the transmission detector, and thus a simultaneous detection of high-density and low-density substances can be realized, the detection effect of the object to be detected can be optimize, and the detection accuracy can be improved.
