1. NAME AND TITLE
GADRAS-DRF-19.4.0: Gamma Detector Response and Analysis Software–Detector Response Function.
2. CONTRIBUTORS
Sandia National Laboratories, Albuquerque, NM.
3. CODING LANGUAGE AND COMPUTER
C#, Fortran, C++. (P00610PCX8606)
Full feature set in Windows binaries provided for embedded system analysis
4. NATURE OF PROBLEM SOLVED
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.
5. METHOD OF SOLUTION
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.
6. RESTRICTIONS OR LIMITATIONS
Radiation transport and advanced analyses capability has been removed.
7. TYPICAL RUNNING TIME
Interactive.
8. COMPUTER HARDWARE REQUIREMENTS
Windows based 64-bit systems.
Linux binaries compiled for a variety of system architectures.
9. COMPUTER SOFTWARE REQUIREMENTS
For Windows, recommended 4 GB RAM, 1 GHz processor or better.
For Linux embedded analysis, recommended 128 MB RAM and 500 MHz processor or better.
