Electromagnetic spectrum
An electric and magnetic disturbance traveling through space at the speed of light
Electromagnetic radiation
The maximum height of a wave
Amplitude
The distance between the peak of one wave to the peak of the next one (m)
Wavelength
The number of waves passing a given point each second (Hz)
Frequency
The removal of an electron from an atom
Ionization
The atom and the electron that was removed from ionization
Ion pair
High energy particles with the ability to ionize matter
Particulate radiation
Particle consisting of two protons bound to two neutrons with a net positive charge and the ability to ionize matter
Alpha particulate
An electron that is emitted from an unstable nucleus with the ability to ionize matter
Beta particulate
A general term for the process by which an atom with excess energy in its nucleus emits particles and energy to regain energy
Radioactivity
The process of a radioactive element giving off excess energy and particles to regain stability
Radioactive decay
Elements that are composed of atoms with unstable nuclei
Radioactive
The length of time it takes for half the remaining atoms in a quantity of a particular radioactive element to decay
Used to measure radioactivity
Half-live
Positively charged beta particle
