PURPOSE: A portable radiation detector with a radiation alarming function is provided to inform a man in service with a buzzer guiding alarming sounds and alarming signals on a real time basis when exposure of radiation is sensed. CONSTITUTION: A portable radiation detector with a radiation alarming function comprises an optical fiber, the radiation detector(100), a signal amplification unit(200), a time extension unit(300), a lamp part(500), a buzzer part(600), and a voice guidance unit(400), and a sensing number counter unit(700). The radiation sensor converts radiation signals input through the optical fiber into electrical signals, thereby sensing the electrical signals. The signal amplification unit amplifies measured current and outputs to the time extension unit. The time extension unit extends the signals. The lamp unit displays flicker signals for a predetermined period. The buzzer unit outputs alarming sounds repetitively for a predetermined period. [Reference numerals] (AA) Voice IC notification
