Comparative Study of SAR from Mobile Phones With and Without Headset

Abstract - Mobile phones have become the most commonly used electronic products. I can hardly imagine the world without mobile phones now. The radio frequency signal generated by the mobile phone is transmitted as electromagnetic radiation (EMR). EMR penetrates semi-solid materials, especially human tissues, and can cause dielectric heating. This effect is divided into thermal radiation and nonthermal radiation. The skin near the skull area of ​​the ear is very thin compared to other parts of the body.

When speaking on mobile phones, we are exposed to a certain amount of electromagnetic waves. It occurs mainly in the signal transmission between the mobile phone and the mobile base station. SAR shows how much radiation from mobile phones is absorbed by our organization. If your cell phone SAR is low, it is even better. The highest level permitted by the FCC is 6 watts per kilogram of body weight. In Europe, the EU Council recommends a SAR limit of 0 W / kg as described here.

Just as a food must be labeled with nutrients, the phone must list its radiation output. Today I would like to list 10 best and lowest SAR phones. If you do not know what the SAR is, you can read it here. The following list is based on the data released by the monthly German newsletter "Connect" on "communication" which has been tested on mobile phones since 1993. There is currently no established standard for SAR in the mobile phone industry as government action does not require it. Some brands disclose information on SARs, others do not. Furthermore, do not forget that SAR is not the only radiation. Unfortunately, I do not know much about any other radiation.

But there is good news for you! Mobile manufacturers are currently deploying various models with limited SAR (SAR) restrictions. However, compared to the effect of the phone, there is one thing certain. They have many advantages. It is really beneficial for you to use these gadgets safely.
