Abstract: A microwave hazard alarm that indicates the presence of microwave radiation from microwave ovens or other transmitting sources by means of a light indicator. The alarm comprises a handheld microwave receiver including an antenna, a detector, a battery powered amplifier, a light emitting diode and a unique circuit connecting the components on a small printed circuit board. The indicating light emitting diode (LED) blinks on and off periodically when the detected microwave power level is safe and below a predetermined power level. At greater power levels the LED stops blinking and glows continuously.
