The demonstration version is accompanied by a tutorial, and a set of twelve example cases. The Demonstration Guide provides step-by-step instructions for developing the tutorial case and for modifying and running the example cases. The examples, which include several based on International Atomic Energy Agency (IAEA) material, are:

• three separate models assessing different aspects and designs for near-surface waste disposal facilities;
• a safety assessment model for legacy disposal of naturally occurring radioactive material (NORM);
• a model for atmospheric dispersion and deposition of NORM radionuclides from the stack of a coal-fired power station;
• a biokinetic model for lead behaviour in the human body;
• models for radionuclide releases to the biosphere via (i) contaminated irrigation water and (ii) groundwater discharges to a small lake catchment;
• a Gaussian plume model within an atmospheric deposition source term;
• a probabilistic biosphere model from the Nuclear Energy Agency PSACOIN model inter-comparison exercise;
• a model for C-14 migration in an aquatic system; and
• a model for migration of carbon dioxide and methane from landfill disposal of municipal waste.

In addition to providing those potentially interested in purchasing AMBER licences with hands-on experience of using the code, the demonstration version has been designed with its potential use as a free teaching tool in mind. The tutorial provides users with a simple model that they can implement for themselves and then use to explore modelling of contaminant migration and potential impacts.
