ABSTRACT:
A personal radiation-alerting device for use with a cellular telephone is provided. The radiation alerting device may comprise a radio frequency (RF) sampling unit adapted to measure the amplitude of the electromagnetic field generated by the cellular telephone over time, a computing unit adapted to compute the amplitude over time and to compare it with a predefined reference level and an alerting unit adapted to output an alert whenever the electromagnetic field exceeds the predefined reference level.
