ardent comic fans would have you know, prolonged exposure to harmful radiation can be hazardous to our health. But before you start looking out for radioactive spiders or a tank containing toxic waste, remember that the danger is closer to home than you think.
The culprit? That trusty mobile phone you depend on for work and pleasure. In order for it to run large applications or transmit strong signals for clearer calls, the mobile phone has to be powerful.Unfortunately the more the power it has, the more radiation we are exposed to. Here are some tips that may help limit your exposure to radiation.
1. Buy a Low–radiation Phone
SAR stands for ‘Specific Absorption Rate’ and is an indication of the amount of radiation that is absorbed into your head while you are using your mobile phone. The higher the SAR value, the more radiation that’s absorbed your head.
SAR values are usually expressed in units of watts per kilogram (W/kg) in either 1g or 10g of tissue. To err on the side of caution, the Europe Limit states that your phone should not exceed 2.0 W/Kg in 10g of tissue, while the Australian and US limit takes more precaution with a cap at 1.6 W/Kg.
For your own safety, you should do your own research on the phone model that you intend to buy. In this case, lower is better!
2. Use a Headset or Speaker
While some headsets (especially the Bluetooth wireless variety) do emit radiation, it’s considerably less than if you were to hold the phone right next to your ear. So if you’re the sort who loves to hold long conversations on your phone, do invest in a headset.
To be even safer, try using the speaker mode whenever possible. Yes, it’s more awkward, and you have less privacy, but it also greatly reduces radiation to the head. If you are alone in a private place like your bedroom, you may want to choose this option. Otherwise, texting works just as well too!
3. Keep your Distance
Keep your phone as far away as possible from your body to limit exposure. In fact, refrain from putting the phone next to your ear immediately after dialling. Give it a few seconds because the radiation pulse that occurs as your phone is attempting to place a call is the strongest.
Another thing to take note: try to limit your phone’s direct exposure to soft body tissues by keeping it in your bag. Avoid carrying the phone on your person in a pocket or wearing it on a lanyard hanging down your chest.
4. Ditch the Case
They may look pretty or add to your ‘bling bling’ factor, but phone cases may reduce connection quality, force the phone to transmit at a higher power and increase our exposure to radiation as a result.
5. Poor Signal = MORE Radiation
If you think that a poor signal (lower signal bars on your phone) means lower radiation, you’re sadly mistaken. In fact, a poor signal means that your phone has to work harder aka emit more power (radiation) in order to place a call.
In other words? Avoid making phone calls when you are in an area with poor signal or risk a higher exposure to radiation.
6. No-No to Children and Mobile Phones
Yes, most of our young ones are already more techsavvy than the adults. But parents should delay giving a phone to a young child as a child’s brain absorbs twice the amount of radiation as compared to an adult.
7. Give Yourself a Radiation Break
Before you turn in for the night, turn off your phone or leave it as far away from your person as possible. Make the effort to give yourself a radiation break before the day begins again.
For most of us, our mobile phones are practically our best friend. But for the sake of our health, let’s play an active role in limiting our exposure to phone radiation!
