Electromagnetic radiation alerting device for use with a cellular telephone

DETAILED DESCRIPTION The striking deficiencies of existing technologies, outlined above, lead to the inescapable conclusion that there is a pressing need for radiation warning devices that measure cumulative exposure to electromagnetic radiation over time, in accordance with recognized standards such as the ICNIRP standard.
Some embodiments of the present invention seeks to provide portable early radiation-warning electronic device of small dimensions and low cost that may be attached to a cellular telephone.
The device may be attached to the antenna of a cellular telephone, directly to the body of the cellular telephone or to the replaceable cover of cellular telephone.
Alternative, according to some embodiments of the present invention the device may be integrated in the battery of the cellular telephone or in the cellular telephone itself.
In accordance with some embodiments of the present invention, a 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 peak and average 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.
There is also provided in accordance with some embodiments of the present invention a radiation-alerting cellular telephone battery.
The battery may comprise a current sampling unit adapted to measure indirectly the amplitude of the EW generated by a cellular telephone during its active transmission time.
There is also provided in accordance with some embodiments of the present invention a radiation-alerting cellular telephone.
The cellular telephone may further comprise RF sampling means or may use existing sampling means.
The activation and sensitivity setting for the alert may be installed from a dedicated menu on display of the cellular telephone or a factory set with default values may be installed during manufacture
