Is EMF protection necessary for iPad?

Not necessary. There's a lot of bunk online about radiation levels. And that's just what it is - bunk. The Earth puts out more radiation than that every day.

you been growing up surrounded by emf signals from a lot! more powerful sources than wifi, Bluetooth or cellular, and those originate from broadcast FM and TV signals

I guess the OP doesn’t know about the Y2K scare. I have a dozen Y2K compliant mouse pads for sale.
