Owing to high X/γ-ray absorption coefficient, high carrier mobility lifetime product, and low temperature solution growth, halide perovskites emerged as promising room temperature radiation detector materials, which outperform traditional high-purity Ge and CdZnTe materials in term of low-cost, chip compatibility and large-area imaging. Starting from the fundamental properties of halide perovskites and the principle of radiation detectors, the development of halide perovskite radiation detectors since 2015 was briefly introduced. Then, recent progresses of direct radiation detectors (intensity, imaging, energy spectroscopy) and indirect scintillator detectors were systematically reviewed, and the crucial factors for high-performance detectors were discussed, which could provide valuable guidance for further boosting performance of halide-perovskite-based radiation detectors in future.
