Is radiation really harmful for our bodies?

Is radiation really harmful for our bodies ?

This is a very important question we should ask especially in this period were most countries are connecting the 5th generation cell phone network called 5G.

Before listing the scientific publications and research done in this domain I want to outline three important things: 

1-Telecommunication companies usually spend very much on funding researches to says that it is not harmful and if somebody makes a publication that opposite to them they will fund a research to attack it and make it weak .
2- they will also pay a lot of money to the government to ensure their business goes on smoothly like installing the towers on government buildings to pay them rent and make them benefit. 
3- It is just a matter of time till the publications will be more and more every day ... just like cigarettes that started many years ago as a healthy  thing advertised by doctors ! then turned out to be the opposite. Exposure to radiation for a long time need to have a long term research with fund to support these researches. There are always a lack of budget for this.

Below is some of the resources and you could easily google and fine much more.
