Hello people
I want to ask that radio waves can be harmful for living things? ( I know the some em waves such as gamma or x-ray also microwaves can be harmful ) If it is, how ? or why? then what is the limit of radio waves to be safe. I ask because, gamma rays or x-rays have some specific units such as gray or sievert for calculaion of effect of these radiation to living things. I know these are high energetic radiations not like radio waves . Also are these units can be used for radio waves ? Therefore if it is not, which frequency of em wave can effect minimum harm ? What is the limitation ?
Thanks for your all comments...
