Abstract:

AMBER is a flexible, graphical-user-interface based tool that allows users to build their own dynamic compartmental models to represent the migration, degradation and fate of contaminants in an environmental system. AMBER allows the user to assess routine, accidental and long-term contaminant release. 

Specifically, AMBER:  

- Is a complete performance assessment tool 
- Incorporates a fast and accurate Laplace-transform solver and numerical time-step solver 
- Allows time-varying source terms and transfer processes which may be linear or non-linear 
- Allows the import/export of data with external files 
- Has 'units awareness' 
- Can be applied probabilistically  
- Has built in graphing as well as Excel export capabilities 
- Is easy to use and apply  
- Allows the user to tailor the results format.

AMBER allows the user the flexibility to define: 

- Any number of compartments 
- Any number of contaminants and associated rates of degradation (both compartment dependent and independent) 
- Any number of transfers between compartments 
- Sub-models within larger models 
- Algebraic expressions to represent transfer processes operating between compartments 
- Algebraic expressions to represent the uptake of contaminants by humans and other output quantities of interest 
- Non-linear transfer processes (e.g. solubility-limited leaching) 
- Deterministic, probabilistic and time varying parameter values.

VI. Additional remarks

commercial software applied widely to understand the impact on humans (and other biota) from radiological contaminants. Becoming more widely applied in non-radioactive fields.
