• Both electromagnetic and particulate radiation

• Neither electromagnetic nor particulate radiation

What is the origin of Fast neutron radiation?

• Radioactive decay

• Fission

• Moderation

• Fusion

Why do neutrons not react electrically with the electron cloud of the atom?

• Because they are charged particles

• Because they are uncharged particles

• Because they are high-energy particles

• Because they are low-energy particles

What happens to neutrons during physical collisions with atomic nuclei?

• They gain energy

• They lose energy

• They remain unchanged

• They convert into protons

What type of energy is transferred in the case of electromagnetic radiation?

• Kinetic energy

• Potential energy

• Thermal energy

• Energy of photons

What happens to the energy in the process of excitation?

• It is absorbed by an electron

• It is emitted by an electron

• It is scattered by an electron

• It is reflected by an electron

What type of radiation is encountered in ordinary visible light?

What happens when ionising radiation traverses a medium?

• Charged particles bounce from one site of interaction to another and leave a trail of ionised particles

• The medium becomes completely ionised

• The radiation loses all its energy
