About Us

Our Mission

Actinia’s mission is to increase the resolution and decrease the dose used in radiological imaging techniques such as SPECT, CT, and even plain X-rays. Actinia develops cutting-edge radiation detector materials that allow for a halving of the dose, or doubling of the resolution, of common imaging techniques used in medicine and security.

History of Discovery

We initiated our research on CsPbBr3 (CLB) and related materials in the late 2000s as potential hard radiation detector materials. Our first report in 2013 identified CLB as a very promising inorganic semiconductor detector with good X-ray response.

In 2018 we demonstrated that CLB can reach <4% energy resolution for γ-ray detection using CsPbBr3 detectors. Specifically, our planar perovskite detector resolved the 59.5 keV (241Am γ-ray), 122 and 136 keV (57Co γ-ray), 511 keV (22Na γ-ray) and 662 keV (137Cs γ-ray) lines. For 57Co γ-ray spectra, a planar perovskite detector achieved energy resolution (ER) of 3.8%.

In 2020, our CLB detector resolved 137Cs 662 keV γ rays with 1.4% energy resolution, as well as other X-rays and γ-rays with energies ranging from tens of keV to over 1 MeV.
