3. Cell Phones Radiation
In order to estimate the dangers coming from the use of mobile phones, I present you a few things about it.
In the top picture on the left, you see a "classic" FDTD simulation of electromagnetic absorption inside a model “human head” made by a composite material for a mobile phone working at 915 MHz with power 1 W (SAR is the Specific Absorption Rate to electromagnetic radiation).
In the following graph on the left, you can see the change of safety limits by frequency for Electric Field, Magnetic Field and Energy Flux. In the case of the previous simulation the safety limits are not achieved.
The maximum magnetic field has been found 1.04 A/m against 0.1 A/m, which is the safety limit at frequency 915 MHz. Also, the maximum SAR has been found 1.87 W/kg against 1.6 W/kg, which is the safety limit for the same frequency.
