We have developed a radiation detection application for smartphones and tablets, that allows users to easily observe and monitor cosmic rays. Cosmic rays are radiation particles that originate from outer space and pass through our bodies at a rate of over 100 particles per second. This application enables users to observe these cosmic rays, which are invisible to the naked eye, in a simple and accessible way. The app was developed and made available through a joint research project with the HIBINO Laboratory in the Department of Applied Physics at Kanagawa University.
