Mobile Phones and Health: 12 tips to avoid risks DAS

For ten years, the radio frequencies emitted by mobile phones are subject to various studies and research to highlight the potential harmfulness of these waves . Measured in watts per kilogram (W / kg) , the famous SAR ( specific absorption rate for ) indicates the amount of energy absorbed by the body. European legislation has set a ceiling of 2 W / kg while across the Atlantic the maximum allowed radiation is 1.6 W / kg.

If WHO wants to be reassuring and a decree dating from 2003 requires manufacturers to indicate the DAS on their products, according to the precautionary principle , it is better to choose a mobile with the lowest possible SAR and follow these recommendations. See our ranking of mobile according to their SAR .

                              

1 - Teens under 15 should not have access to a mobile . This basic rule is not, however little or respected by parents. The adolescent is particularly vulnerable to electromagnetic radiation.

2 - Avoid contact of a cell phone with the belly of a pregnant woman. Again, it is a basic common-sense advice , the cells of the embryo are very sensitive to radiation emitted by mobile.

3 - Avoid approaching the mobile phone within 20 cm of cardiac or other metal implants implant.

4 - When buying a new laptop , choose a model with SAR value is as low as possible , preferably less than 0.7 W / kg.

5 - Avoid wearing your mobile at or against the heart , armpit , hip or genitals ...

6 - Prefer the use of a wired headset to keep mobile phones away from your brain and your ear. Better to use a wired rather than a wireless headset which delivers waves headset.

7 - Limit the number and duration of calls. On average, no more than 6 calls per day not to exceed 3 minutes each. The ideal is to meet an average time of 1 hour 30 minutes between each call.

8 - Telephone under conditions of maximum reception! If you make a call while you are receiving the wrong network , DAS issued by the notebook can be multiplied by 2 or 4 !

9 - Do not call the move.

10 - Do not call in the car or any other metal infrastructure. The effect of " Faraday cage " traps and reflects the waves emitted by the laptop.

11 - To avoid passive exposure to radiation, move away from the public when you make a call .

12 - Never store a lit or charging less than 50 cm from your head overnight phone.
