Review Article : Applicable methods of evaluating peak area of gamma ray spectra

Gamma ray spectra have interesting information about energy and intensity of gamma photons. Normally, this is available in the peak area background region. A full sits on a continuum produced by absorption high photons, while region Compton scattering The most essential concern errors method determining events both areas. uncertainty low when counts are small relative to counts. However, it becomes with respect that background. detection threshold for ultimately determined This depends technique used form spectra. paper reviews different methods their associated uncertainties terms principle application techniques used.
