Can radio waves be harmful?

Repeated Wi-Fi studies show that Wi-Fi causes oxidative stress, sperm/testicular damage, neuropsychiatric effects including EEG changes, apoptosis, cellular DNA damage, endocrine changes, and calcium overload .

Some people are concerned about the potential health effects of RF energy from wireless technology. Most studies haven’t found any health effects from cell phone use . A few studies have connected RF and health effects, but scientists have not been able to repeat the outcomes. This means that they are inconclusive.

Limit guidelines in U.S. are from 200 uW/cm 2 to 1000 uW/cm 2 (2 W/m2 to 10 W/m2) for RF radiation depending on frequency. Countries developed different standards based on either *Thermal Effects *Non-Thermal Effects or *Precautionary Considerations.

Scientific evidence suggests that cancer is not only linked to mobile phone radiation and that other factors also may be involved in its development. Most mobile operators use from radiofrequency waves in the range up 300 MHz to 3 GHz that can be harmful for human health (1).

The WHO/International Agency for Research on Cancer (IARC) has classified radiofrequency electromagnetic fields as possibly carcinogenic to humans (Group 2B), based on an increased risk for glioma, a malignant type of brain cancer, associated with wireless phone use.

The safe limit for a mobile phone user is an SAR of 1.6 watts per kg (1.6 W/kg), averaged over one gram of tissue , and compliance with this limit must be demonstrated before FCC approval is granted for marketing of a phone in the United States.
