Using a mobile phone to surf the Internet, make calls or send text messages, which one emits the most radiation?

Talking on the phone radiates the most because it is closest to the head, especially the moment the connection is made.

The radiation from the Internet is relatively large for pregnant women, because Internet access is a continuous radiation, and the stimulation lasts longer. However, since ordinary people use the Internet far away from their heads, and the radiation is emitted in the form of cube roots, the radiation becomes almost negligible as the distance is long
