You can’t imagine your world without the phone; whether you’re commuting, or you are at work, or in your bed - all the time a phone remains with you. Your proximity with smartphones, more often than not, raises a question that whether radiation emission from these phones acts on your health. There have not been enough scientific studies to prove that cell phone radiation can have damaging effects on your health. However, this evokes another question - how much radiation is discharged by smartphones? The German Federal Office for Radiation Protection recorded specific absorption rates (SAR) of smartphones that emit most radiation and found that currently the smartphone oozing out the highest level of radio waves is Mi A1 from Chinese company Xiaomi. The SAR of this smartphone is 1.75 watts per kilogram.
According to the list, the phone with the least SAR ie 1.24 is iPhone 7 Plus. The maximum cell phones discharging radiation on the list are produced by Chinese companies; however, names of American companies also appear on the list. Which Type of Radiation is Discharged by Cell phones? To find the answer to this question, first you should understand the types of radiation. There are two types of radiation - ionizing and non-ionizing. X-rays, UV and gamma rays are ionizing radiation that is extremely powerful to break apart atoms. On the other hand, non-ionizing radiation includes but not limited to infrared lights, waves from light bulbs and tube lights, oven, people, megahertz light from cell phones, and gigahertz light from Wi-Fi. These waves are not harmful because they don't have enough power to break apart chemical bonds; however, the effect can be detrimental if they are emitted in large doses. Whether your cell phone radiation is harmful can be determined if you know about the frequency that it emits. Cellular frequencies can vary between 450 to 2000mtz. Initially these frequencies at the time of making a call can be up to 2 Watts; however, it can go down up to .02 Watts few seconds later. If you compare this emission with ionizing radiation by a microwave oven, you will find that they would be hundreds of times more than a cell phone oozes out. Though cell phones radiation can’t be deleterious to your health, taking precautions is not a bad idea.

Could you provide the list of other phones that discharge greater radiation?
