Alfa Rift was founded by specialists with backgrounds in radiation detection, optics, and nuclear instrumentation. Our team's collaboration began at the Finnish Radiation and Nuclear Safety Authority (STUK) and Tampere University of Technology, where we conducted research on alpha particle detection.
Building on years of joint research in alpha–gamma coincidence spectroscopy, alpha imaging, and radon detection, we develop practical and reliable solutions for radiation safety and environmental monitoring.
Our mission is to bring advanced sensing technologies from the laboratory into the field — combining scientific precision with robust engineering.
