Will a small piece of cellphone screen that is missing emit more radiation?

Cell phones emit low levels of non-ionizing radiation when in use. The type of radiation emitted by cell phones is also referred to as radio frequency (RF) energy. As stated by the National Cancer Institute, "there is currently no consistent evidence that non-ionizing radiation increases cancer risk in humans.

The antenna, which is the primary “radiation” ingress/egress end point, outside the motherboard (the latter is shielded), is not part of the screen.

A screen protector may help keep it together, until you get another one.

It's non-ionizing radiation and in a tiny amount even if you took the whole antenna out (pretty much by design; otherwise you'd have to carry around a car battery in order to keep the phone running for the day).

Also the display isn't designed to be a RF shield, I don't think the phone would go above the nominal SAR levels reported on the manual even if you took the screen or part of the screen out, but someone more expert than me may correct me if I'm wrong on how the measurement is taken. In any case the difference should be minimal / insignificant.

It's the glowy part of the screen that's emitting the radiation, and it's non-ionizing radiation, also known as "light," so it's nothing to worry about.

I saw a promotion from one major carrier that they are giving new phones for free if you sign a contract

I think you're safe tbh. You definitely need to replace that phone soon though.

That is a very interesting question, I will need to google that for the answer.

Lol, no. :)

yep; any day now you'll turn into a giant green rage monster... 🤔

No but my phone did that i put on a clear screen cover to stop it

engineer here. can confirm: yes, marginally. you'll be exposed to more RF radiation but it's not nearly enough for your body to even notice. use handsfree or speakerphone until you get it repaired / replaced
