Clever practical tips for reducing cellphone EMF’s

Practical Advice to Limit Exposure to Electromagnetic Radiation Emitted from Cell Phones

  1. Explain to your children why you cellphones are powerful devices, how they work and why it’s best to be mindful about their usage. Personally, I think a good way to start this conversations is to tell your kids about the magic of technological advancement, and explain to them that NO ONE had a cell phone 20 years ago! It’s fun to see when kids wonder about a world before GPS and all of that. That can lead into a conversation about why we don’t really know what cell phones can do to our bodies in the long-term – and that’s the truth.

Do not allow children to use a cell phone, except for emergencies. The developing organs of a fetus or child are the most likely to be sensitive to any possible effects of exposure to electromagnetic fields.

2. EMF amplitude get exponenentially smaller the farther away you keep the phone.  While communicating using your cell phone, try to keep the cell phone away from the body as much as possible. The amplitude of the electromagnetic field is one fourth the strength at a distance of two inches and fifty times lower at three feet. Whenever possible, use the speaker-phone mode or a wireless Bluetooth headset, which has less than 1/100th of the electromagnetic emission of a normal cell phone. Use of a hands-free ear piece attachment may also reduce exposures.

4. Avoid carrying your cell phone on your body at all times. Do not keep it near your body at night such as under the pillow or on a bedside table, particularly if pregnant. You can also put it on “flight” or “off-line” mode, which stops electromagnetic emissions.

Alex Stadtner note: On the iPhone it’s called “airplane mode” and accessed from the primary “settings” icon that looks like gears. Putting it in airplane mode will stop RF (radio frequency) transmission, but there are still lower frequency magnetic fields emitted from the phone while it is on.

 

Keep cell phone face pointing towards you (check with August)

If you must carry your cell phone on you, make sure that the keypad is positioned toward your body and the back is positioned toward the outside so that the transmitted electromagnetic fields move away from your rather than through you.

Alex Stadtner note: On the phones we’ve tested this does appear to be true because of intentional shielding or the strategic location of the phone’s antenna in a location less likely to be obstructed (by your head).

6. Only use your cell phone to establish contact or for conversations lasting a few minutes, as the biological effects are directly related to the duration of exposure. For longer conversations, use a land line with a corded phone, not a cordless phone, which uses electromagnetic emitting technology similar to that of cell phones.

Landline > cordless phone > texting > Short phone call     In order of preference.

7. Switch sides

Switch sides regularly while communicating on your cell phone to spread out your exposure. Before putting your cell phone to the ear, wait until your correspondent has picked up. This limits the power of the electromagnetic field emitted near your ear and the duration of your exposure.

Alex Stadtner note: Some studies have shown a correlation between which side of the head a cell phone user holds the phone and where tumors develop.

8. Avoid cell phone use in cars or trains!

Avoid using your cell phone when the signal is weak or when moving at high speed, such as in a car or train, as this automatically increases power to a maximum as the phone repeatedly attempts to connect to a new relay antenna.

Alex Stadtner note: Another great reason not to use your cell phone in the car is you’re inside a metal box! RF travels like a bullet – but is easily ricocheted whenever it hits metal. Transmitting RF in a metal cage leads to RF bouncing around several times before exiting the vehicle and increasing overall exposure levels. We did an interesting test using a plug-in cell phone cradle connected to an external car antenna and found reductions of RF inside the car above 50%.

9. When possible, communicate via text messaging rather than making a call, limiting the duration of exposure and the proximity to the body.

10. Choose a device with the lowest SAR possible (SAR = Specific Absorption Rate, which is a measure of the strength of the magnetic field absorbed by the body). SAR ratings of contemporary phones by different manufacturers are available by searching for “sar ratings cell phones” on the internet.
