To ship an excepted package for limited quantities of Class 7 (radioactive) materials under 49 CFR 173.421, the package's activity per package must not exceed the limits in Table 4 of § 173.425, and you must meet the following specific requirements:
* General Design: Each package must meet the general design requirements of § 173.410.
* Radiation Level: The radiation level at any point on the external surface of the package cannot exceed 0.005 mSv/h (0.5 mrem/h).
* Surface Contamination: Non-fixed contamination on the external surface must not exceed the limits specified in § 173.443(a).
* Package Marking: The outside of the inner packaging (or the outside of the packaging itself, if there is no inner packaging) must be marked with the word “Radioactive.” Additionally, the package must bear the UN identification number marking described in § 173.422(a).
* Fissile Material: The package must not contain fissile material unless it is excepted under § 173.453.
* Preparation: The material must be otherwise prepared for shipment as specified in accordance with § 173.422.
If these conditions are met, the package is excepted from requirements for specification packaging, labeling, shipping papers (provided it is not a hazardous substance or waste), and the rest of the subpart.
