These are general findings. As I say, the main concern is on the long-term lower-level effects of electromagnetic fields.
As mentioned, we are still at the beginning of our exposure, meaning possibly 10 or 20 years of mainly mobile phone usage. We believe that further investigation is needed. Replication of studies with positive and negative effects also is needed. I believe that further research, mainly on children, is important in this regard. Of course, more epidemiological studies based on the effects on the brain are also needed.
There is an important need for deeper studies on the interaction mechanisms of electromagnetic fields with biological systems, and in that area we can say that little work has been done so far.
