Our country will not grading experts say that cell phone radiation must pay attention to the SAR value

In South Korea in preliminary recently by "tagging mobile phone radiation level" bill, the Chinese mobile cellphone to related to testing department consultation, at present our country has not further degree of cell phone radiation set grading plan, but related expert proposal, users still needs to pay attention to the mobile phone radiation, and mobile phone SAR value as low as possible.

Inspection agency says every phone have radiation that value

Earlier, South Korea in the new law recently, South Korea's wireless communication equipment manufacturers and importers must since June 2012, in mobile phones and tablet computer on the outer packing, mark electronic radiation intensity level, make consumers need not measurements will know the real damage radiation. The bill is expected to be held recently in the formal meeting adopted.

To this, the Chinese mobile phone related to testing department says, there is no research degree of cell phone radiation set classification plan, because the Chinese cell phone actually competent departments of cell phone radiation has always attached great importance to the problem, in each of the net every mobile phone through testing requirements than mark radiation absorption rate (SAR) value, a little bit careful as long as the users check every phone in the manual with the SAR value, we can know the actual situation of the mobile phone radiation.

Specifically, our country on August 1, 2008, it introduced the mobile phone electromagnetic radiation exposure limits local "mandatory standards, requirements mobile phone radiation absorption rate than before they leave the factory (SAR) must be 2.0 w/kg or less, and need to be in the mobile cellphone noted.

Some phones SAR value contrast

Mobile phone radiation has been a controversial topic is the medical profession, and also has caused the user's concern. As early as in 2000, the United States mobile communication industry association (CTIA) passed a regulation, request to have the CTIA authentication of the mobile phone will make the phone to consumers to radio waves level or effective absorption rate (SAR) tips. Data for organisms that SAR (including the human body each unit kg allow absorption radiation, the SAR value represents radiation effects on the body, is the most direct test values.

The international community has been a CDMA and GSM mobile phone radiation struggle, generally, CDMA mobile phone radiation than GSM mobile phones low. Was this really the case? In fact in the mobile phone in the specification of the mark of the SAR value to compare. Nokia (the Po) to GSM or WCDMA standard give priority to, its N8 the SAR value of 1.02 mobile phone w/kg, N97 is 0.67 watt/kg, C3 to 1.09 watts/kg, 5230 is 1.10 watt/kg. SONY Ericsson mobile phone system of basic and nokia, the mobile phone U_1 of SAR value of 1.58 watt/kg, T707 for 0.62 w/kg.

But CDMA mobile phone MOTOROLA (the Po) ME811 marked clearly on the manual of the SAR value of 0.447 watt/kg; China telecom (the Po) to HTC (the Po) customized a CDMA/GSM mobile phones "double qing S" the specification of the last page also the SAR value standard for 0.447 watt/kg.

The mobile phones on the market is the main sales model, and the mobile phone can see that contrast, CDMA phone SAR value less than GSM mobile phones generally. But these mobile cellphone there is no doubt that meet the national standards, only, SAR value is lower, the mobile phone radiation is absorbed the quantity is less.
