Of a spectrum of
γ-radiation
, the part of the spectral response curve corresponding to the
absorption
in the
radiation detector
by the
photoelectrical effect
of the detected γ-energy. In most cases the peak also contains events caused by multiple processes and use of the expression
total absorption peak
or
total absorption peak
is to be preferred. Synonymous with photopeak.
