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 modelled 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 modelled with parameter values chosen by the user.
