Electromagnetic radiation, within the bandpass used, emitted by, and/or in the case of atomic absorption spectroscopy, absorbed in, the atomizer when nothing is supplied to the atomizer but the gases involved in its operation.
Note:
In the case of flame atomic spectroscopy, the term "flame background" is used.
