Is nuclear radiation different from other radiation such as electromagnetic that causes it to be harmful?

Everyone knows nuclear radiation is harmful when exceeding a certain limit. Is it different from other forms of radiation such as electromagnetic radiation from electronic devices? Like if I got blasted with some sort of super WiFi would I be harmed in the same way as nuclear radiation?

There is radioactivity, which is energy emitted when an atom breaks down, and electromagnetic radiation, of which light is a form.

Electromagnetic radiation starts at radio and increases to microwave (wifi is classed as microwave), then infra-red, then visible, then UV, x-rays and gamma rays.

You can hold your phone against your skull for hours without any ill effects, because the power output is low. OTOH you can put a pig’s head in a microwave and its eyes explode.

High UV, x-rays and gamma rays are all ionizing, that is they will knock bits off your DNA and give you cancer.

There are three forms of radioactivity: alpha particles, beta and gamma rays. Alpha particles (a helium nucleus of two protons and two neutrons) are the most easily stopped, but if they do penetrate they will play havoc with your parts.

Beta particles, or electrons, have medium penetration and can cause damage to DNA.

Gamma rays, a form of electromagnetic radiation, are hardest to stop but do least damage.

So you could make super wifi, depending on how you define it. If standard wifi is microwave you could simply increase the power and boil your eyeballs, or you could ramp up the frequency until you get x-rays or gamma rays, both of which can turn you into a spider with superpowers, but issues too.
