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 Ongoing Research page.


Large studies in progress



Cosmos is a cohort study of mobile phone use and health. The study will investigate the possible health effects of long term use of mobile phones and other wireless technologies. It is an international study being conducted in five European countries United Kingdom, Denmark, Sweden, Finland, the Netherlands and France. The study will follow at least 200,000 participants for 20 – 30 years.



MOBI-KIDS is an international multi-centre case-control study on risk factors for brain cancer in young people. MOBI-KIDS aim is to evaluate the possible association between communication technology and other environment exposures and the risk of brain tumours in young people. Between 2010 and 2015 nearly 1,000 young people aged 10 to 24 years with brain tumours and about 2,000 healthy persons were invited to participate in the study. The study will use two approaches to characterize exposure from mobile phones: (1) self-reported history of use, including duration and type, and (2) using methods to estimate the amount of RF energy absorbed in the brain at the tumor location.


National Institute of Environmental Health Science (NIEHS)

The National Toxicology Program (NTP) headquartered at NIEHS is leading the largest laboratory rodent study to date on cell phone radio frequency. The NTP studies will help clarify any potential health hazards from exposure to cell phone radiation. The studies are designed to mimic human exposure and are based on the frequencies and modulations currently in use in the United States.

The NIEHS is also funding researchers at the University of California, Los Angeles, to study whether exposure to cell phones in childhood can affect the nervous system.
