Biological process

cellular response to electromagnetic radiation stimulus, cellular response to radiation stimulus

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an electromagnetic radiation stimulus. Electromagnetic radiation is a propagating wave in space with electric and magnetic components. These components oscillate at right angles to each other and to the direction of propagation.

Note that 'radiation' refers to electromagnetic radiation of any wavelength.
