The following links are from government agencies and other organizations who review public health and radio frequency exposure.
Electromagnetic Fields and Cancer- NIH National Cancer Institute
No consistent evidence for an association between any source of non-ionizing EMF and cancer has been found.
Cell Phone Towers - American Cancer Society
Public exposure to radio waves from cell phone tower antennas is slight for several reasons. The power levels are relatively low, the antennas are mounted high above ground level, and the signals are transmitted intermittently, rather than constantly.
Base Stations and Wireless Technologies - World Health Organization
Considering the very low exposure levels and research results collected to date, there is no convincing scientific evidence that the weak RF signals from base stations and wireless networks cause adverse health effects.
Easy to Read Summaries of Scientific Opinions - European Commission
The results of current scientific research show that there are no evident adverse health effects if exposure remains below the levels set by current standards.
Mobile phone base stations: radio waves and health - UK Public Health England
...although a substantial amount of research has been conducted in this area, there is no convincing evidence that RF field exposures below guideline levels cause health effects in adults or children.
Radio Frequency Safety - Federal Communications Commission
The information on this page provides answers and information to inquiries regarding RF Safety.
These organizations review and make recommendations on radio frequency exposure
ICES - International Committee on Electromagnetic Safety
International Committee on Electromagnetic Safety (ICES) is responsible for development of standards for the safe use of electromagnetic energy in the range of 0 Hz to 300 GHz
ICNIRP - International Commission on Non-Ionizing Radiation Protection
As an independent organization, the International Commission on Non-Ionizing Radiation Protection (ICNIRP) provides scientific advice and guidance on the health and environmental effects of non-ionizing radiation (NIR) to protect people and the environment from detrimental NIR exposure.
The Health Physics Society - has a comprehensive Ask the Expert section with a selections of Q&A's on Cell Phones, Radiofrequency Radiation, and Powerline Fields.
