US government agencies conclude there is no scientific evidence proving that cell phones cause cancer or other health problems. The Federal Communications Commission (FCC),  US Government Accountability Office (GAO),  and the US Food and Drug Administration (FDA),  have all concluded that there is no evidence in the scientific literature proving that cell phones cause brain tumors or other health problems. According to the FDA, "attempts to replicate and confirm the few studies that did show a connection [between cell phone radiation and head tumors] have failed." 
Last year, 15-year-old English schoolgirl Jenny Fry was found hanged in woodland near her home. According to her parents she suffered from electrical sensitivity, making it impossible for her to sit in WiFi classrooms and have WiFi at home. The school refused to remove the WiFi. Speaking at the inquest her mother said, “I believe that WiFi killed my daughter.”
Children may have an increased risk of adverse health effects from cell phone radiation. According to American Academy of Pediatrics President Dr. Robert Block, when cell phones are used by children, "the average RF energy deposition is two times higher in the brain and 10 times higher in the bone marrow of the skull," than for adults.  A July 2008 peer-reviewed study shows that children under the age of eight absorb twice the amount of radiation into their brain tissue as adults due to their lower skull thickness.
