Health & Safety/RF Emissions
Wireless phones emit low levels of radio-frequency (RF) energy during use. Based on scientific data currently available, T-Mobile has not determined that RF energy from wireless phones causes health risks. Nonetheless, we want our customers to be informed as the wireless industry and government agencies continue to monitor the ongoing scientific research on this important subject.
The U.S. Federal Communications Commission (FCC) has established standards governing the RF energy emission levels for all wireless phones sold in the United States, as well as RF energy emissions from cellular towers, in order to protect the health of the general public.
You may have heard the terms SAR or SAR value. SAR stands for Specific Absorption Rate, which is a measure of the rate of absorption of RF energy in the body. The FCC has established maximum SAR values for wireless phones in the United States. Since 1996, the FCC has set the maximum SAR value for handheld wireless phones at 1.6 watts per kilograms, averaged over one gram of tissue. A wireless phone model must be tested by the manufacturer and certified to the FCC to not exceed this limit before it may be made available to the public. Because the SAR value is determined using the phones highest power level, the actual SAR level of a phone while operating may be less than the reported SAR value. You can contact your phones manufacturer or refer to its user manual to learn more about its SAR value.
Scientific studies have not shown a conclusive relationship between wireless phone use and health problems.
You may have heard reports that RF exposure from wireless phones presents a health risk. Global health organizations and government agencies have conducted scientific research on the potential health effects of RF exposure, and have determined that the available scientific evidence does not conclusively show a relationship between wireless phone use and health problems. The FCCs website explains that, while research is ongoing, [t]here is no scientific evidence that proves that wireless phone usage can lead to cancer or a variety of other problems, including headaches, dizziness or memory loss.
· Following the World Health Organizations (WHO) release of the largest study to date on cell phone use and brain tumors, the Interphone Study, the U.S. Food and Drug Administration (FDA) commented that while research was ongoing, the available scientific evidence including the [Interphone Study] shows no increased health risk due to radiofrequency (RF) energy.
· The FDA also noted that a separate National Cancer Institute (NCI) program found that occurrences of brain cancer did not increase between 1987 and 2005, despite a dramatic increase in cell phone use during those years. The NCIs bulletin explains that [c]oncerns about the potential health effects of using cellular telephones . . . and specifically the suggestion that using a cell phone may increase a persons risk of developing brain cancer are not supported by a growing body of research on the subject.
· The FDA has also reported on WHO's International Agency for Research on Cancer (IARC) classification for RF energy. IARC reviewed the medical literature regarding RF energy, and classified it in Group 2B (possibly carcinogenic to humans), which means there is limited evidence showing radiofrequency carcinogenicity in humans and less than sufficient evidence of carcinogenicity in experimental animals. For perspective on what this means, IARC has also classified, among other things, coffee, pickled vegetables, and talcum powder in Group 2B.
If you are interested in limiting your exposure to RF energy, you can:
· Reduce the amount of time you spend using wireless phones
· Use a headset or other hands-free device
· Carry your wireless phone away from your body
· Text or email (but dont text or email while you are driving)
