The invention discloses coincidence detection equipment for radioactive measurement. The coincidence detection equipment comprises a frame, a detector arranged on the frame and an air inlet and outlet interface, a gas measuring chamber is arranged in the frame; the frame is a semi-regular polyhedron and comprises a triangular surface and a square surface, and the detector is arranged on the square surface; the detector is a cadmium zinc telluride detector. The detection equipment disclosed by the invention is particularly suitable for radioactivity measurement of radioactive xenon, and overcomes the defects that a high-purity germanium gamma spectrometer and a NaI + plastic scintillator beta-gamma coincidence detector are large in size, heavy in weight, difficult to maintain, not easy to carry, not easy to measure on site and the like; a lower detection limit can be achieved, and compared with a NaI detector, the device has higher measurement precision; the appearance of the detector adopts a semi-regular pol
