We’ve all become very reliant on mobile phones, simply because they’re an awesome invention. But even so it is probably prudent to minimize extensive exposure to the radiation from the handsets during a long call. And before you trot out the old nonsense about non-ionizing radiation being completely safe, just remember that microwave ovens also use non-ionizing radiation, which most definitely is not safe unless properly shielded.
Tawkon is a free Android app which monitors radiation output from your phone’s sensors and calculates your exposure at different times and locations. The app then delivers automatic alerts if it thinks the level is too high (e.g. if you’re talking for a long time from a location which is far away from a cell tower, thus requiring a stronger signal between you and the tower).
The app has been tested by Satimo, a certified US test lab, and confirmed as offering an accurate SAR test tool. The alerts take the form of advice to switch from holding the phone to your ear, to using a hands-free option such as speakerphone or a headset, and because the radiation count is cumulative over a month, it’s valuable for keeping track of when you’re overdoing it generally, not just per incident.
This kind of monitor is particularly useful for younger members of the family, because they are the ones more susceptible to potential problems from over use of long phone calls because of their thinner skull structure. No matter which side of the debate you’re on regarding possible issues with prolonged use of mobile phones, it must make sense to take precautions until more definitive information is available, especially where children are concerned.
