Actinia produces room‑temperature inorganic perovskite radiation detectors using high‑purity CsPbBr₃ crystals that deliver low dark current, high energy resolution, and broad energy coverage. Their scalable crystal‑growth process enables detectors that can halve patient radiation dose or double imaging resolution for medical scanners, and provide affordable, high‑sensitivity gamma‑ray monitoring for nuclear security applications.

Problem
Medical imaging modalities such as X‑ray, CT, and SPECT expose patients to ionizing radiation, and the image quality of many existing detectors limits diagnostic confidence. In parallel, nuclear safety and security operations require high‑resolution gamma‑ray detection that is both sensitive and affordable, yet current semiconductor detectors are costly and difficult to scale.
Solution
Actinia develops all‑inorganic halide perovskite detector materials, primarily cesium lead bromide (CsPbBr₃), that operate at room temperature with low dark current and high charge transport. Their proprietary crystal‑growth processes produce large, high‑purity single crystals suitable for mass production, enabling detectors that can halve the radiation dose or double the spatial resolution of conventional imaging systems. The material’s wide bandgap and chemical stability provide robust performance across a broad energy range, from tens of keV to >1 MeV, making it applicable to both medical imaging and nuclear security. By replacing more expensive semiconductor alloys, Actinia’s detectors lower system cost while delivering superior energy discrimination and sensitivity. The technology is positioned to improve patient safety, enhance diagnostic imaging, and support reliable monitoring of nuclear facilities and illicit material detection.
