A microsystem for measuring alpha radiation and processing radiation dose is presented. The radiation sensor is built on a PIN diode. The measurement results are transmitted wirelessly to a host computer. Under defined measurement conditions the peak spectrum of the radiation can be exactly calculated. In real-world environments sources of alpha radiation can be detected.
