Ask a professional: the house I rent is on the top floor, and there are many TV satellite receiving lines on the roof of my house. I want to ask, are these radioactive?

The main function of these instruments is to receive, and the function without emission is very subtle, so there is basically no radiation, so don't worry. If you really don't like them. . . You can call the Radio and Television Bureau and make sure that they will disappear in a few days. But be anonymous, or you can't live here in the future.
