4G phones might mean more exposure to radiation
India is waiting with bated breath for the nationwide coverage of 4G, just like we waited for 3G to change our lives a few years ago. I have been on a 4G SIM for the past couple of weeks, and wherever I can get the signal in Delhi-NCR, the internet speeds are faster and pages do open up a tad faster.
But there will be something about the new 4G phones that no one will discuss, and that is how these phones with a better signal strength will emit more radiation. Technically, anything that can send out or receive signals emits a certain amount of radiation. Most of it is within limits of human endurance though, we are not built to adapt to systemic waves — every thing has radiation, but natural radiation is not systemic. This is why sustained exposure to cell phone radiation over long periods of time — like when you carry your smartphone in your pocket the whole day, or leave it under the pillow overnight — could have serious health implications. According to the US Federal Communication Commission (FCC) all phones sold within the US come within the recommended levels of RF energy, still it suggests that it is better to keep the phone a safe distance away if you “must conduct extended conversations”. The safe distance suggested is between 5mm and 25mm. So keeping the phone next to your ear is certainly not recommended.
