What is radiation?
Energy that is transmitted by waves through space or matter
A type of electromagnetic wave that is only used for medical imaging
The transfer of heat through the movement of fluids (liquids or gases)
The process of heat being transferred from a hotter object to a colder object through direct contact
What is energy?
The capacity to operate or work
A tangible substance that can be seen, touched, and created
The rate at which work is done
A force that pushes or pulls an object
What is ionization?
Any process by which a neutral atom gains or loses an electron, thus acquiring a net charge
The process by which an atom or molecule becomes more stable by losing or gaining protons
A process where an atom's electrons move to a higher energy level but remain within the atom's electron shells
The process of a neutral molecule splitting into smaller, neutral molecules
Ionization is harmless
Sound is a form of mechanical energy
