An electromagnetic radiation detector

An electromagnetic radiation detector comprises a probe for detecting the objects of generating electromagnetic radiation, a current amplifier for the electromagnetic radiation signals detected by the probe, a current meter displaying the amplified electromagnetic radiation signals, and a horn. The utility model enables to detect the strength of the electromagnetic radiation in certain distance to the probe. If the radiation is too strong, the governmental environment monitoring station is called to redetect whether the strength exceeds the national standard. The utility model is an environmental product preventing people from the electromagnetic radiation.
