# §173.424. Excepted packages for radioactive instruments and articles.


A radioactive instrument or article and its packaging are excepted from requirements in this subchapter for specification packaging, labeling, marking (except for the UN identification number marking requirement described in [§ 173.422(a)](/cfr/49/173.422.md?p=a)), and if not a hazardous substance or hazardous waste, shipping papers and the requirements of this subpart if:

- (a) Each package meets the general design requirements of [§ 173.410](/cfr/49/173.410.md);
- (b) The activity of the instrument or article does not exceed the relevant limit listed in Table 4 in [§ 173.425](/cfr/49/173.425.md);
- (c) The total activity per package does not exceed the relevant limit listed in Table 4 in [§ 173.425](/cfr/49/173.425.md);
- (d) The radiation level at 10 cm (4 in) from any point on the external surface of any unpackaged instrument or article does not exceed 0.1 mSv/hour (10 mrem/hour);
- (e) The active material is completely enclosed by non-active components (a device performing the sole function of containing radioactive material shall not be considered to be an instrument or manufactured article);
- (f) The radiation level at any point on the external surface of a package bearing the article or instrument does not exceed 0.005 mSv/hour (0.5 mrem/hour), or, for exclusive use domestic shipments, 0.02 mSv/hour (2 mrem/hour);
- (g) The nonfixed (removable) radioactive surface contamination on the external surface of the package does not exceed the limits specified in [§ 173.443(a)](/cfr/49/173.443.md?p=a);
- (h) Except as provided in [§ 173.426](/cfr/49/173.426.md), the package does not contain more than 15 g of uranium-235; and
- (i) The package is otherwise prepared for shipment as specified in [§ 173.422](/cfr/49/173.422.md).
