Warm bodies emit infrared radiation.
Rn-222 emits alpha radiation.

The Wienβs law for maximum intensity is, Here, is the wavelength of maximum intensity and T is the temperature of human body. Rearrange the above expression for . Substitute for T to find . So the maximum energy is radiated at 9355.83nmK. Humans emit infrared off radiation which is electromagnetic radiation with a frequency lower than visible light.
One way to look at electronic radiation might be to see it as the electromagnetic energy radiated by electronic equipment as a function of their operating circuits. Current technology is replete with myriads of complex electronic devices, and these all emit low power electromagnetic radiation that is generated within their circuitry. That is the nature of electronics. We get that radiation even though we might not want or need it. From this perspective, we can differentiate that kind of radiation from the kind we see that is intentionally generated for transmission to facilitate wireless communication between devices.
Warm bodies emit infrared radiation.
Hot gases of any kind emit electromagnetic radiation.
Other than visible light used to scan the original to be copied, some heat, and the kind of very low and extremely low frequency electromagnetic radiation emitted by all electrical devices, photocopiers do not emit radiation.
Black holes are believed to emit something called Hawking radiation.
A pulsar is a special kind of neutron star, which is the ultra-dense leftover core of a massive star. Pulsars emit beams of radiation that sweep out in circles as the pulsar spins. When those beams flash over Earth, we see them as regular, repeating pulses of radio emission.

Yes, although probably not the kind you're thinking about. Microwaves use electromagnetic radiation to heat food. If the microwave is properly constructed and not damaged, none of that radiation escapes.
