Federal Communications Commission (FCC):
Since 1996, the FCC requires all wireless communications devices sold in the United States to meet its minimum guidelines for safe human exposure to RF energy. These guidelines and rules are based upon standards developed by the Institute of Electrical and Electronics Engineers (IEEE), the National Council on Radiation Protection and Measurements (NCRP), as well as input from other federal agencies, including the Environmental Protection Agency (EPA), Food and Drug Administration (FDA), the National Institute for Occupational Safety and Health (NIOSH), and the Occupational Safety and Health Administration (OSHA). These guidelines specify exposure limits in terms of Specific Absorption Rate (SAR). The SAR measures the rate of electromagnetic frequency (EMF) energy absorbed by the body.
The guidelines stipulate the following:
All mobile and portable transmitting devices are subject to routine environmental evaluation for radio frequency exposure prior to equipment authorization or use.
SAR limit on wireless devices is 1.6 watts per kilogram (W/kg).
Food and Drug Administration (FDA):
In partnership with the FCC, the FDA sets policies and procedures in place for wireless phones in the United States. The FDA continuously monitors the effects of RF energy on health. The FDA believes that the weight of scientific evidence available does not show any association between exposure to RF from cell phones and adverse health outcomes.
Environmental Protection Agency (EPA):
Wireless technology has become an increasingly controversial topic, as the use of technology continues to increase. However, the RF energy generated by wireless technology is nonionizing, meaning experts say it is not strong enough to affect the structure of the atoms it contacts. The EPA has concluded that there is not enough evidence to suggest that there is any cause and effect relationship between RF energy and cancer. If you are interested in seeking more information on radiation, the EPA has dedicated a website to radiation, including the most common forms individuals are exposed to daily.
World Health Organization (WHO):
There are a number of studies that have investigated the effects of RF energy on health over the past two decades. However, these studies contain an inadequate amount of evidence to establish a causal relationship between RF exposure and adverse health effects. According to the WHO, short-term tissue heating is the only interaction between RF energy and the human body that occurs. In May of 2011, the International Agency for Research on Cancer (IARC) classified RF energy as being possibly carcinogenic to humans, meaning there is limited evidence to say RF energy causes cancer in humans, and less than sufficient evidence of RF energy causing cancer in experimental animals. Other everyday items joining RF energy in this category include coffee, pickles, talc-based powder and gasoline exhaust.
It is important to note that today's 3G and 4G phones emit less radio frequency energy than their counterparts that were used more than a decade ago. Furthermore, according to the WHO, any large risks associated with exposure to RF should have been detected in the studies that have been conducted to date. Time trend studies monitoring occurrences of brain cancer have not shown trends or evidence affected by mobile phone use. This also pertains to leukemia, lymphoma and other adverse health effects.
