Cellphones use frequencies extremely close to the microwave region of radaition employed in the communication industries.

As we have said before, microwave frequencies are noxious to humans AND those who live within the microwave radiation pathway between/contiguous to these communicaton towers are at a much higher risk to the longterm ill-effects of these radiations over time esp. if you are one these 6% of humanity who are disposed to these ADD/ADHD patterns.

Of course whilst many folk move homes/apartments regularly OTHERS might well remain in the one home for many years.
Indeed, if you live within 200 metres of the communication zone pathways then, for those 10-14 hrs a per day you remain within these fields,  your cells will be more subject to the 'cell-wall-blocking' effect which has now been strongly linked to the damage done to cellular toxin builup within cells exposed to these fields.
