Radiation does not require particles not because it is particles but because radiation only happens in space and in space there is no particles the "radiation" on earth is not pure radiation.

Which of the heat transfers does NOT require the presence of particles?
radiation
Does radiation involve heat passing through particles?
Heat doesn't pass through particles. On an atomic or sub-atomic level, heat is the speed with which the particles are either vibrating or moving. Some kinds of radiation are related to the temperature of the particles that emit the radiation, other kinds are not.
Why can heat travel through space by radiation but not by conduction or convection?
Because conduction and convection require particles to transfer heat. Space is a vacuum (has no particles in it) so convection and conduction cannot occur.
Does radiation require the presence of particles of matter?
Not necessarily.If you are referring to the spectrum of electromagneticradiation like gamma, X, UV, visible, infra red, thermal,microwave, shortwave, radio/TV waves, they are pureenergy radiation.If you are referring to the radiation emitted by radioactiveelements you have:Alfa radiation. Consists of high energy (kinetic energy)helium nucleus (particles).Beta radiation. High energy (kinetic energy) neutrons (particles).Gamma radiation. Very small wavelength Electromagneticradiation (pure energy).
Why cant thermal radiation move through space by conduction or convection?
Because in space there are no particles (this is called a vacuum), however conduction and convection require particles to work eg. solids, liquids and gases have particle arrangements. So thermal radiation has to travel through space via radiation as space is a vacuum and particle-less.

What roles do radiation play in heating and cooling the earth?
Radiation transfers heat from one object to another. It does not require any particles unlike conduction and convection. Radiation travels in the form of electromagnetic waves.
Is gamma not considered a type of radiation ray?
Actually, gamma is the ONLY type of radiation ray. Since the three types of radiation are alpha particles, beta particles, and gamma rays, and the other two are particles, technically, gamma rays are the only radiation rays. If that is not what you are looking for, then I recommend rephrasing your question.
What radioactive emission is not a particle?
Gamma rays are not particles, but highly-ionizing electromagnetic radiation of a very short wavelength.The other major atomic "radiation" is in the form of alpha particles (He nuclei) or beta particles (electrons, or positrons).
What helps keep a penguins skin dry?
Radiation is a type of heat transfer that does not require particles . how does the color of the penguin skin help it?

Is ultraviolet radiation hot?
Radiation is particles of energy. The reason you get hot while standing in the Sun is because the particles energize your cells and other materials which causes vibrations, leads to friction, and generates heat.

Is radiation a measure of the average kineic energy of the particles in an object?
No, radiation is not a measure of the average kinetic energy of particles in an object. Radiation refers to the emission of energy as electromagnetic waves or particles from a source. The energy of radiation can vary depending on the type and source, and it is not directly related to the average kinetic energy of particles in an object.
Is there particles in radiation?
yes
