Summary
Computer codes estimate atmospheric release consequences for radionuclides and chemicals. Different models are needed for emergency planning versus immediate response actions.
Area of Science:
- Environmental Science
- Chemical Engineering
- Nuclear Engineering
Background:
- Accurate consequence assessment is crucial for managing atmospheric releases.
- Various computer codes exist to model these events.
Purpose of the Study:
- To provide brief descriptions of common computer codes.
- To highlight the differing requirements for emergency planning and response.
Main Methods:
- Review and description of existing atmospheric release consequence estimation codes.
- Categorization of codes based on complexity and input needs.
Main Results:
- Commonly used computer codes for radionuclide and chemical releases are described.
- Code selection depends on whether the application is for planning or immediate response.
Conclusions:
- The choice of atmospheric consequence modeling software is critical.
- Tailoring code sophistication to the specific needs of emergency planning or response enhances effectiveness.
