radiation
Invisible energy transmission
Radiation is energy traveling through space as waves or particles.
The term covers everything from visible light and radio waves to the more dangerous X-rays and gamma rays associated with nuclear processes.
Radiation therapy uses targeted energy to kill cancer cells.
Heat radiates from a fire; influence radiates from a center of power.
The pattern of spreading outward from a source connects all uses.
