Central Registry Toolbox Code Version(s):  V2.10.1
Code Owner/Developer:  Pacific Northwest National Laboratory (PNNL)

GENII is a second generation of environmental dosimetry computer code compiled in the Hanford Environmental Dosimetry System (Generation II). GENII provides a state-of-the-art, technically peer-reviewed, documented set of programs for calculating radiation dose and risk from radio nuclides released into the environment. The GENII System includes capabilities for calculating radiation doses following postulated chronic and acute releases.

In May 2004, the Department of Energy (DOE) performed an evaluation of GENII against DOE’s safety software quality assurance criteria. A gap analysis report was generated that identifies the strengths and weaknesses based upon ASME NQA-1 criteria.  Upon completion of this evaluation, GENII V1.485 and 2.0 were listed in DOE’s safety software Central Registry as safety analysis toolbox codes.

In August 2013, DOE completed an evaluation of GENII V2.10.1 against DOE’s safety software quality assurance criteria and this version was listed as a Toolbox code in the safety software Central Registry. The evaluation report is posted on the Safety Software Communication Form (SSCF) at https://sscf.energy.gov/.
