Radiation protection detector

The utility model provides a radiation-proof detector which comprises a single axis magnetic induction sensor, a signal detecting circuit, a single chip circuit, a sound-light alarm, an LCD display circuit, a keystroke circuit and a voltage stabilizing circuit. The radiation-proof detector is characterized in that the signal output terminal of the single axis sensor is connected with the signal input terminal of the signal detecting circuit, the level output terminal of the signal detecting circuit is connected with the A/D input terminal of the single chip circuit, the drive signals of the sound-light alarm circuit and the LCD display circuit come from the corresponding signal output terminals of the single chip, the output terminal of the keystroke circuit is connected with the command input terminal of the single chip, and a stabilized power source supplies the required working voltage for all the circuits. The utility model provides quantitative analysis data for eradication of the environmental electromagnetic pollution so as to protect the environment. The device is convenient to carry and easy to operate and is an ideal electromagnetic radiation detection instrument.
