If you do a web search on "EMF radiation" beware! Most of the sites are trying to sell you some magic trinket to ward off the EMF demons.
Our honest opinion is that there is likely some risk for some people, and little risk for others. There is a big grey area in between with professional scientists arguing both sides.
It is always important to try to separate the hype from the truth. Educating yourself about the facts and being aware what risks are present in your environment will best position you to assess your risk.
This website linked below does a pretty good job of explaining the various types of EMF and what risks there may be, and don't seem to have an agenda.
