Radioactive material which is not certified as Special Form is referred to as “Normal Form.” The standard shipping instructions are based on the assumption that both sources in a gauge are Special Form. When one or both of the sources are Normal Form, the standard instructions are no longer valid.
The following sections explain the modifications necessary to ship a 3400 series gauge in which the Cs-137 is Normal Form and the Am-241 is Special Form.
