InterSpec is a peak-based spectral analysis app for gamma and x-ray radiation detected by NaI, CsI, LaBr, HPGe, CZT, or similar detector types. InterSpec assists in performing nuclide ID, fitting for source activity, shielding amounts or types, and nuclide ages. It also has a number of useful tools related to gamma radiation, including: peak fitting, dose calculations, nuclide decay references, nuclide decay calculator, gamma/xray/reaction reference lines, handles self attenuating sources, energy calibration, spectrum file meta-data data editing, opens most spectrum file formats and exports to a number of common formats, and more.
