GENII-LIN project: a multipurpose health physics code to estimate radiation dose and risk from environment contamination

GENII-LIN is an open source radiation protection environmental code with capabilities for calculating radiation dose and risk to individuals or populations from radionuclides released to the environment and from pre-existing environmental contamination. The code can be used for purposes such as siting facilities, environmental impact statements, and safety analysis reports. The code can handle exposure pathways that include: external exposure from finite or infinite atmospheric plumes; inhalation; external exposure from contaminated soil, sediments, and water; external exposure from special geometries; and internal exposures from consumption of terrestrial foods, aquatic foods, drinking water, animal products, and inadvertent intake of soil. The flexible modular structure and the strictly object oriented software design simplify code improvement and patching: other modules can be added and the present ones updated, with minimal effort.
