Ionizing radiation is any radiation that creates:

Ionizing radiation is defined as any radiation that has enough energy to remove tightly bound electrons from atoms, creating charged particles. This process is known as ionization. When ionizing radiation interacts with matter, it can knock electrons out of their atomic orbitals, leading to the formation of positively charged ions and free electrons. This charge creation has significant implications, particularly in the context of biology and physics, as it can lead to various chemical reactions within cells and can be harmful to living organisms.

The other choices do not accurately define the effects of ionizing radiation. Heat waves, for example, refer to the transfer of thermal energy but do not involve the creation of charged particles. Light emissions pertain to electromagnetic radiation that might not have the energy required for ionization and typically involves the excitation of electrons within an atom but does not remove them entirely. Sound waves involve pressure vibrations in a medium, which is unrelated to the effects of radiation on atomic structure. Thus, the option related to charged particles directly captures the key characteristic of ionizing radiation.
