Might the cancer risk due to use of cellular phones be greater in children than in adults?
The NCI study included only adults (age 18 years or older at the time of brain tumor diagnosis), and few children used cell phones prior to 1994,so there are no data concerning possible risks among children. Certain agents known to cause cancer of the brain and nervous system in rats (e.g.ionizing radiation or certain chemicals) have the greatest effect when administered very early in life, while the nervous system is developing. However, the situation with cellular phones is somewhat different insofar as exposure to non-ionizing radiation from cell phones has not been demonstrated to cause brain tumors in humans or experimental animals of any age. 11. How do cellular phones work? Cellular technology provides a two-way radio communications system between a portable handset and the nearest base-station. A given geographical region is divided into zones or cells, each of which is equipped with a base station. The base station receives radio frequency signals from cell phones and sends ra
