本条款规定了放射性仪器和制品的例外包装条件。若满足特定辐射水平、活度限制及封装要求，此类货物可豁免规格包装、标签、标记（UN编号除外）、运输单据及部分子章节要求。核心指标包括：10厘米处辐射剂量率不超过0.1 mSv/h，包装表面不超过0.005 mSv/h（专用国内为0.02 mSv/h），且非固定污染符合限值。该规定旨在简化低风险放射性物品的物流合规流程。
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)), 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;
- (b) The activity of the instrument or article does not exceed the relevant limit listed in Table 4 in § 173.425;
- (c) The total activity per package does not exceed the relevant limit listed in Table 4 in § 173.425;
- (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);
- (h) Except as provided in § 173.426, 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.
