AN ELECTROMAGNETIC RADIATION ALERTING DEVICE FOR USE WITH A CELLULAR TELEPHONE

摘要

A personal radiation-alerting device (20) for use with a cellular telephone (10) is provided. The radiation alerting device (20) may comprise a radio frequency (RF) sampling unit (100) adapted to measure the amplitude of the electromagnetic field generated by the cellular telephone (10) 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.
