Hi, I am doing the research on RF radiation.Recently, I tested cell phone for Rf reading with my meter when playing online videos.Some time it goes upto 10000me/sq.meter at cm distance of the phone.Anthony.expert said that most cell phone have 2watts output,then how it is possible to measure 10000mw/sq.meter?It is your meter fault.I informed the company.Their reply is below.
Assume your phone antenna size is 1 square cm, and the power is 2w. So the RF density on your phone antenna is 2w/square cm. Because 2w = 2000mW. It also be 2000mW/square cm.
Because 1 meter is 100cm, so 1 square meter is 100*100 = 10000 square cm.
Covert mW/square cm to mW/square meter need to times 10000 on both.
So, 2000mW/square cm is 20000000mW/square meter.
They said that most phone have0.2_2 squarecm antenna. Is that true if a phone have 1cm sq.and 2watts ,that will be 2w/sq.cm? Why not in 2w/sq.meter? Their convertion from sq.cm to sq.m is true.But how can be a cell phone transmit maximum 20000000mw/sq.meter? Or their statement is wrong? What is the powerdesity maximum(in me/sq.meter) can be of a cell phone having 2 watts ? Best regards
