(ORTEC: Oak Ridge, TN) -- The ORTEC Products Group of AMETEK Advanced Measurement Technology has released ANGLE Version 5, a software application for calculating efficiency calibrations for high purity germanium and sodium iodide gamma spectroscopy systems.

ANGLE Version 5 brings a major update to the efficiency modeling algorithms with numerical integration being replaced by Monte Carlo methodology and cascade summing corrections applied to nuclide branching ratios. A variety of default materials to define common sample matrices is also included, along with the ability to save calculation results and model images to new file formats.

“ANGLE is an excellent tool to address radioactive source management and complex sample matrix challenges,” says Ken Embury, ORTEC product manager. “The new Monte Carlo modeling algorithm and determination of nuclide branching ratios corrected for coincident cascade photon emission are key features that significantly improve gamma spectroscopy system measurement accuracy.”
