  Discussing mobile phone safety with young people
  Sarah Starkey
  British Journal of School Nursing, Vol. 6, Iss. 9, 11 Nov 2011, pp 434 - 438
  The UK Chief Medical Officers recommend that children and young people under the age of 16 years use mobile phones for essential purposes only. But many young people use their mobile or smart phones throughout the day and keep them switched on close to their bodies during the night. Simple steps to reduce exposure to the electromagnetic fields emitted (...)

• Important New Russian Research on Cell Phone Radiation’s Effect on Cognitive and Other Functions in Children. “Our recent 4-year monitoring of effects from cell phone radiation on children, published in Radiation Biology. Radiation Ecology (Volume 51, No.5, 2011), demonstrates an increase in phonemic perception disorders, abatement of efficiency, reduced indicators for the arbitrary and semantic memory and increased fatigue. Over the four-year monitoring of 196 children ages 7-12 who were users of mobile communication devices, a steady decline in these parameters from high values to bottom standards compared was observed. The short-term and long-term potential consequences for society from exposing children to microwave radiation from cellular communication devices must be immediately acknowledged, globally, and responsibly addressed.”
