You've possibly read that France may ban the sale of the iPhone 12 due to high radiation. Read the following:

"The ANFR recently tested 141 mobile phones and found that when the iPhone 12 is held in a hand or carried in a pocket, its level of electromagnetic energy absorption is 5.74 watts per kilogram, higher than the EU standard of 4 watts per kilogram."

Tech blogger Kim Komando posted the following info on smartphone radiation. You''l note in her report the iPhone 12 doesn't show the level of radiation as the above paragraph. Hmmm?..
