How much radiation does a TV transmitting antenna emmit?

In a radius of 5 km for example. And, does the amount of radiation go up in proportion to the amount of antennas? Lastly, what is the amount of radiation a human can take?How much radiation does a TV transmitting antenna emmit?
You are not confusing the radio wave radiation with "atomic" radiation are you? They are quite different with different risks.



There is no way to answer your question as it depends on how much radio energy is being fed to the antenna(s). for example, a micro transmitter can be just 5W, while a powerful TV transmission antenna can be over half a million Watts.



It gets more complicated unfortunately as you have to also take into consideration what frequencies are being transmitted, as some some are more readily absorbed by the human body than others.



So you would need to know all the antennas in a given area and their power outputs at each frequency transmitted. Your absorption would then depend on where you were stood and where and when you move.



You would also have to know id the antennas were isotropic or not (that is, do they emit the radio waves evenly in all directions, or are they directional?) Most microwave links for example are very highly directional, so emit almost no energy other than in the direction the antenna is pointed.



I am sorry, this is probably not helping you, but there is no easy answer I'm afraid. I can tell you that radio waves follow the "inverse square" law, so that means if you stood one metre (or yard) away from the antenna, then someone two metres away would get 1 / 2^2 = 1/4 of the radio waves you do. If they were three metres away, then it would 1 / 3^2 = 1/9 the radio power and so on.



All this assumes there are no obstacles in the way either, since they can block the radio waves or even reflect them.



Even the professionals when testing new transmitters are reduced to driving around the area while test transmissions are carried out, to measure the radio power in that area and see if is good enough and nothing is interfering with it!



The number of antennas does not really give a very good indication I'm afraid, since one really powerful one could be putting out more power than all the others combined, or they could all be really low power, or even be high power, but directed away from you.How much radiation does a TV transmitting antenna emmit?
its actually coming out of the screen , that why they say never sit to close to a tv...now-a-days TV 's have improved and the radiation is very minimal !!1How much radiation does a TV transmitting antenna emmit?
Redcorn no know... Me guessy it no too bad though or they would no be allow to do under law of land.. Good luck find better answer!
