Are Cell Phones Dangerous to Our Health?

Cellphone use has become widespread since the 1990s, and some scientists are concerned that adverse health effects may result from their long-term use.

The Facts

• Cellphones release radiofrequency waves, which are a form of radiation. There are concerns that they may increase the risk of cancers, especially of the head and nervous system.

Research Studies

• Most of the studies conducted so far have not found a link between cellphone use and brain cancer, but a few longer-term studies have found a small increase in risk. More research on exposure across at least 10 years is needed. A number of scientists have raised concerns that some of the research, funded by the cellphone industry, has been biased.

Considerations

• Exposure to radiation from a cellphone depends on how often it is used, the distance to the nearest base station, the quality of the transmission, how far the antenna is extended, and whether a hands-free device is used.

Other Concerns

• Only a few studies have been conducted on potential health risks other than tumors to the brain or nervous system, and there have not been any conclusive findings. Children may be at greater risk for health effects, but research results have not been conclusive on that either.

Prevention

• Until information on the potential adverse health effects are more clear, the U.S. Food and Drug Administration recommends limiting cellphone use and purchasing a hands-free device, which lowers your exposure to radiation from the antenna.
