PC-CREAM 08®; is a complex model that is divided into several parts for ease of use. The main division of the program is into 'Models' and 'ASSESSOR'.
| ASSESSOR: | The assessment program, forms the pivotal dose assessment role within the system |
| Model: PLUME | Calculates activity concentrations in air, deposition rates and external gamma dose rates from radionuclides in the cloud (cloud gamma) at various distances downwind of the release point. |
| Model: RESUS | Can be used to estimate activity concentrations in air arising from the resuspension of previously deposited radionuclides. |
| Model: GRANIS | Models the transfer of radionuclides through the soil and takes into account the shielding properties of the soil when estimating external gamma doses one metre above the soil surface. |
| Model: FARMLAND | A suite of models that can be used to predict the transfer of radionuclides into terrestrial foods following deposition onto the ground. |
| Model: DORIS | can be used to predict the activity concentrations in sea water, sediments and marine biota for user-defined discharge rates. |
| Model: River models | The Screening model is a simple dilution model which assumes instantaneous equilibrium between the water and river sediments and should be used as a screening tool. The Dynamic model can be used which is a time dependent compartment model and requires a greater amount of input data to run. |

The design of PC-CREAM 08®; is significantly different to that of PC-CREAM 98®; and therefore the format of the input data is not compatible between the two systems. Results from PC-CREAM 08®; can be written to '.csv' files for input into spreadsheet packages such as Microsoft Excel®;.
PC-CREAM 08®; requires 60 MB disc space for installation. Please note that the database size can increase quickly and therefore at least 100 MB of disc space is recommended.
