Unless you are very close to a very strong source of radiation such as a 5G cell tower, you will not have any ill effects on your body except for slight warming of your skin. If you are very close to a strong source, you could potentially get cooked alive, so don't get close to 5G or any other type of microwave radiation source of such power.
Stop fearmongering about radiation when if you even knew the basics about EMF you would know this basic fact.
Non ionizing radiation is not harmful unless very powerful and very close to you.
Very powerful antenna transmitting next to your head may not be the best idea. Especially if you have cell turned on you get a lot of radiation.
