I found the following while searching for additional info concerning cellphone interference issues:
Even though no scientific evidence currently establishes a definite link between wireless device use and cancer or other illnesses, some parties recommend taking the precautions listed below. When considering these precautions, remember that your wireless device only emits RF energy when you are using it and that the closer the device is to you, the more energy you will absorb. Also, some parties assert that any potential health risks are probably greater for children than for adults. Finally, some experts think that low frequency magnetic fields rather than RF energy measured by the SAR possibly are responsible for any potential risk associated with wireless devices. The precautions are:
- Use an earpiece or headset. While wired earpieces may conduct some energy to the head and wireless earpieces also emit a small amount of RF energy, both wired and wireless earpieces remove the greatest source of RF energy from proximity to the head and thus can greatly reduce total exposure to the head. Avoid continually wearing a wireless earpiece when not in use.
- If possible, keep wireless devices away from your body when they are on, mainly by not attaching them to belts or carrying them in pockets.
- Use the cell phone speaker to reduce exposure to the head.
- Consider texting rather than talking, but don?t text while you are driving.
- Buy a wireless device with lower SAR. The FCC does not require manufacturers to disclose the RF exposure from their devices. Many manufacturers, however, voluntarily provide SAR values. You can find links to manufacturer Web sites providing these SAR values on the FCC?s Web site at formatting linkNote that the variation in SAR from one mobile device to the next is relatively small compared to the reduction that can be achieved by using an earpiece or headset.
Other Risks
Some studies have shown that wireless devices might interfere with implanted cardiac pacemakers if used within eight inches of the pacemaker. Pacemaker users may want to avoid placing or using a wireless device this close to their pacemaker.
[Note: defribrillators and combined pacemaker/defribrillator are considered the same as a pacemaker aka pacer]
