Letter Power Density



This figure shows various health hazards at different power density levels.
The vertical axis shows power density in microwatts/m2, it can be converted to  milliwatts/m2 by dividing the vertical scale by 1000.
For example, horizontal line corresponding to 100 microwatts/m2 is equivalent to 0.1  milliwatts/m2. Various health hazards just above this level are: headaches, concentration and sleep problems, fatigue, etc. Whereas, in India, we have adopted 450  milliwatts/m2, which is 4500 times higher.
Similarly, horizontal line corresponding to 1000 microwatts/m2 is equivalent to 1  milliwatts/m2. Various health hazards at this level are: adverse neuro, cardio effects, and increased cancer risk, etc. Whereas, in India, we have adopted 450  milliwatts/m2, which is 450 times higher.

This figure shows various health hazards with residential distance to towers. As one moves away from the towers, health hazards decreased.
