Base Station Research


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.


What are agencies saying about radio frequency risks?

American Cancer Society (ACS) 

ACS Cell Phone Towers (Mobile Phone Base Stations)
Some people have expressed concern that living, working, or going to school near a cell phone tower might increase the risk of cancer or other health problems. At this time, there is very little evidence to support this idea.

ACS Cell Phone Fact Sheet

In summary, most studies published so far have not found a link between cell phone use and the development of tumors. However, these studies have had some important limitations.  So it is important that the possible risk of cell phone exposure continue to be researched using strong study methods, especially with regard to use by children and longer-term use.


Center for Disease Control and Prevention (CDC)

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.

Environmental Protection Agency (EPA)

EPA Wireless Technology Fact Sheet

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.


Food and Drug Administration (FDA)

FDA Cellphone Fact Sheet
Many people are concerned that cell phone radiation will cause cancer or other serious health hazards. The weight of scientific evidence has not linked cell phones with any health problems.


Federal Communications Commission (FCC)

FCC Wireless Devices Fact Sheet

There is currently no scientific evidence establishes a causal link between wireless device use and cancer or other illnesses.


National Cancer Institute (NCI)

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.


National Institute of Environmental Health Science (NIEHS)

NIEHS Cellphone Fact Sheet
Current scientific evidence has not conclusively linked cell phone use with any adverse health problems, but more research is needed.
