At a distance of 5 cm, the microwave radiation from a cellphone has an intensity of 51 W/m². The maximum permissible radiation leaking out from a microwave oven at the same distance is 10 W/m². Compare the average electric fields generated by the two devices - how many times stronger is the electric field that is generated by the cellphone than the maximum permissible field leaking from a microwave oven?

A bluetooth headset has an intensity of 0.08 W/m² at 5 cm distance. If you carry your phone on your belt, 77 cm from the center of your brain, what is the total intensity (headset plus phone) at the center of your brain?

How many times longer than the width of your head (assume 10 cm) is the wavelength of a cellphone transmitting at 1713.4 MHz?
