CDPH Guidelines on How to Reduce Cell Phone Radio Frequency Energy
SFDPH has summarized Ongoing Research studies, Studies and Reviews of the literature and evidence, and Research Agency statements and fact sheets relevant to Mobile Phone Base Stations. This is the Research Agency page.
CDC Cellphone FAQ
Do cell phones cause cancer? There is no scientific evidence that provides a definite answer to that question. Some organizations recommend caution in cell phone use. More research is needed before we know if using cell phones causes health effects.
Some people are concerned about potential health effects, especially on the developing brains and bodies of children. Some studies suggest that heavy long-term use of cellphones could have health effects. Other studies don't find any health effects from cellphone use. Long-term studies on animals exposed to the RF found in wireless networks (Wi-Fi) have, so far, found no health effects. Scientists continue to study the effects of long-term exposure to low levels of RF.
There is currently no scientific evidence establishes a causal link between wireless device use and cancer or other illnesses.
NCI Cellphone Fact Sheet
Although there have been some concerns that radiofrequency energy from cell phones held closely to the head may affect the brain and other tissues, to date there is no evidence from studies of cells, animals, or humans that radiofrequency energy can cause cancer.
