Scattering of radiation in a generally backward direction. In the
assay of
radioactivity, it applies to the
scattering of radiation into the
radiation detector from any material except the sample and the detector. In
light scattering, it is said to occur when the
scattering angle,
, is
. Conversely, forward scattering occurs when
is
