Zusammenfassung:PURPOSE: A design basis accident radioactivity leakage detection technique and a visible light wireless alarm system are provided to detect a design basis accident in early stages by using a photo diode detecting gamma rays. CONSTITUTION: A wireless alarm system(100) is composed of a DBA event detection module(130), a DBA event alarm module(140), a DBA event smart transmission module(150) and a signal generation unit(160). A shield block(110) and an illumination block(120) forms the exterior of the wireless alarm system. The wireless alarm system includes a photo diode(131) to detect gamma rays(21). The DBA event smart transmission module transmits a DBA event detection signal to a main controller.
