Unpopular but entirely correct. The study used power up to ten watts per kilogram. Your phone uses around a watt or less compared to your whole body mass. Let's say the average of 62 kilos. Your exposure is less than a fiftieth of what was produced in the experiment, probably less because you aren't irradiated 24 hours a day--you take it off your person to charge at some point. And the radio produces far less wattage when it's idle, which is going to be the vast majority of your day. Compared to the amount the rats were getting constantly, this would be a truly minuscule fraction of exposure over time.

Even with such extraordinary amplitude, the correlation was very slight. Trust me, everyone has much bigger health risks to worry about than radio. If you've ever had a drink in your life you've done worse.
