A PET scanner does not use electromagnetic radiation.
The subject either consumes or is injected with a radioactive chemical that decays by emitting positrons. These positrons are detected by particle detectors in the scanner and a computer calculates where they came from to generate the image.
What else can I help you with?
What kind of wave is an x ray?
X-Rays are part of the electromagnetic spectrum. Other waves on the electromagnetic spectrum include light, radio waves, and gamma rays.
Is light part of the radio spectrum?
No, light is not part of the radio spectrum. But, both the radio spectrum and light are part of the electromagnetic spectrum. The electromagnetic spectrum is a range of frequencies from very low to very high. Light frequencies are higher than radio frequencies but both are the same kind of thing.
What kind of radiation is used by mobile phones?
Electromagnetic radiation, in the microwave portion of the radio spectrum.
What kind of waves are used in satellite transmission?
Radio waves - in the microwave section of the electromagnetic spectrum.
Which kind of EM wave has he lowest energy?
Radio waves have the lowest energy among the electromagnetic spectrum.
Is light a kind of radiation?
Yes, light is a type of electromagnetic radiation that is visible to the human eye. It falls within a certain range of wavelengths on the electromagnetic spectrum.
what kind of wave is a gamma wave?
A gamma ray is an electromagnetic wave. It has the highest frequency (and energy) as well as the shortest wavelength on any wave on the electromagnetic spectrum.
What kind of wave is a gamma ray?
A gamma ray is an electromagnetic wave. It has the highest frequency (and energy) as well as the shortest wavelength on any wave on the electromagnetic spectrum.
Radiant energy is found in the form of what kind waves?
In Electromagnetic waves
What kind of wave is a electromagnetic wave that measures 30 nanometers from crest to crest?
A 30 nanometer electromagnetic wave would fall within the ultraviolet region of the electromagnetic spectrum. Its short wavelength indicates high frequency and energy, making it potentially harmful to living organisms in large doses.
What type of energy do you feel as heat?
You are feeling a specific kind of light called infrared light. This is not visible light, and it comes before red in the electromagnetic spectrum.
What kind of light can be used to heat your food?
Not radio waves. microwaves are used but they are both part of the electromagnetic spectrum as is visible light, infra-red etc.
