If the classification of a radioactive material is known, you can look it up in the material list (via UN-No. or choose SCO, LSA):

If you suppose that your package contains surface contaminated objects, use the following query to check the measured contamination values:

If the classification is unknown and measured activity values are available, use the query via nuclidlist to determine the classification:

At the end of each query you receive a statement, if you've got radioactive material according to the regulations or not. In the first case a substance list will be displayed with detailed information (eg. classification, names, labelling and marking) about your radioactive material.
