The Surface Contamination Investigation Program (SCIP) is a program for assessing the doses to both transport workers and members of the public from radioactive contamination on the surface of packages. The program models five package types covering the range commonly transported in both the UK and in other countries. These are a small manually handled package, a small remotely handled package, a large remotely handled package, an EU nuclear fuel flask, and a UK nuclear fuel flask. The exposure pathways assessed are from both internal and external irradiation. Internal irradiation results from the inhalation and inadvertent ingestion of material from the package surface. External irradiation is from material present on the skin and from material on the package or from activity that has been deposited onto the ground surface in the vicinity of the package. The package types and pathways used in this current model have been adapted from those described in an earlier model developed by an IAEA Coordinated Research Project (CRP) on this topic.
The methodology used in SCIP V1.1 is based on the CRP methodology. The program allows users to enter their own scenario specific parameters, rather than those defined for the CRP. The same basic four package types have been kept (“small manual,” “small remote,” “large remote,” and a “European fuel flask”) with the addition of a UK specification fuel flask.
A number of different scenarios can be modeled using SCIP V1.1 by entering parameters such as package type, distance from package, time of exposure, and activity concentration on the package. The flexibility of the program allows for other situations to be modeled with parameter values chosen by the user.
The code was developed using Microsoft Visual Basic 6.0 and only the executable is available. Because of the development environment adopted, the code is not portable on platforms other than IBM PC under WINDOWS. Source code is not distributed with this package.
The code is interactive.
Windows based personal computers.

The package is transmitted on a CD disc which contains documentation, installation and executable files, data files and test cases. Source code is not included in the distribution.
