Real-world cell phone radiofrequency electromagnetic field exposures

Abstract

Overview

In 2011, the International Agency for Research on Cancer classified radiofrequency electromagnetic fields (RF EMF) from cell phones as possibly carcinogenic to humans. This was supported by findings from the National Toxicology Program and the Ramazzini Institute, which demonstrated significant increases in gliomas and Schwannomas of the heart in rodent studies.

Findings

• Recent research highlights negative impacts of RF EMF on animal cells and cognitive/behavioral development in children.
• Epidemiological studies suggest a correlation between cell phone use and increased glioma risk, notably at the typical exposure site during regular cell phone use.
• Understanding real-world usage and signal reception differences is crucial in assessing safe exposure levels.
• Exposure measurements across multiple phone models and network operators in the USA revealed dramatically higher RF EMF exposure in environments with weak signal reception.
• Significant reduction of exposure can be achieved by maintaining specific distances or using Bluetooth devices, with Bluetooth exposures being substantially lower than direct phone contact.

Conclusion

The findings emphasize the importance of cautious cell phone use, especially in poor signal conditions, to significantly lower RF EMF exposure levels. These results have guided public health recommendations on cell phone usage.
