I’ve been following this issue casually for some years. Because of the short time this technology has been in use, definitive conclusions are not yet available. Prudent consideration of the information in this article, and understanding of the simple precautions recommended, would seem to be reasonable.
Electromagnetic fields generated by cell phones should be considered a potential human health risk. Sufficient time has not elapsed in order for us to have conclusive data on the biological effects of cell phones and other cordless phones—a technology that is now universal.
Studies in humans do not indicate that cell phones are safe, nor do they yet clearly show that they are dangerous. But, growing evidence indicates that we should reduce exposures, while research continues on this important question.
