Infrared light

The question answers itself: heat, (Heat is thermal by definition.)
ultra volit
Protactinium-231 emit alpha particles, gamma radiations, X-rays.
the answer is thermal
Geothermal energy is thermal energy that is made and stored in the Earth. Thermal energy determines the temperature of things. Geothermal energy can be used for electricity.
The Earth produces geothermal energy. The geothermal gradient is the amount of increase in temperature with depth.
Black holes are believed to emit something called Hawking radiation.
Warm bodies emit infrared radiation.
Hot gases of any kind emit electromagnetic radiation.
Rn-222 emits alpha radiation.
ultra volit
Red laser light.
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.
All electromagnetic wave lengths (light)
Cell phones are small radios, that both transmit and receive. When they transmit they emit radio waves, which is a kind of radiation.
Protactinium-231 emit alpha particles, gamma radiations, X-rays.
Radiation is a kind of thermal energy that can travel through space. The only word properly capitalized is 'Radiation' because it is the first word in the sentence. The noun 'space' is a common noun and should not be capitalized.
These are called "thermocouples".http://en.wikipedia.org/wiki/Thermocouple
