i stay in new jersy and i have a query regarding a subject in my course. since i am a science and technology student, i need to know few details about the cellphone towers. not as how they work, but i am doing a research on a subject that studies nuclear radiations and its effect on living organisms. what is the power level of the cell phone tower? and what divides the geographical area? many research studies say it is a harm for human brain, how radiations prove to be harmful for human brain?
