3. DESCRIPTION OF PROGRAM OR FUNCTION

GADRAS-DRF contains a suite of capabilities related to radiation detection. Its primary function is the simulation of gamma ray and neutron detector signals for radiation sources. It also contains regression analyses and fully automated radionuclide identification. GADRAS-DRF is the public version of the full version of GADRAS; capabilities such as radiation transport and advanced analyses are removed.

4. METHODS

Features in a gamma ray detector spectrum, such as photo peaks and the Compton continuum, are derived from first-principles calculations based on interaction cross sections. Neutron detector response is computed by interpolating on a pre-computed database of thermal (3He) detector responses. For both gamma ray and neutron detectors, the response to radiation that scatters into the detector from the surrounding environment is determined by a combination of first-principles calculations and empirical modeling. For new detectors, known detector parameters such as size and resolution are all that is necessary to compute an initial response function. This response function may be refined by measuring calibration sources and fitting the detector’s parameters to match the data.
