SR-NIEL Calculators (version number 3.6.0) for electrons, protons, ions and neutrons have been embedded into GRAS (Geant4 Radiation Analysis for Space), version 3.4, that runs under Geant4 version 10.1 (patch-03). Instructions how gain access to the code are availabe into GRAS webpage.

This task was accomplished under ESA contract 4000116146/16/NL/HK with title "Non-Ionizing Energy Loss (NIEL) Calculation and Verification".

These additonal tools will be publicly available from the next release of GRAS code.
