2.2.7.2.4.1.5

Uranium hexafluoride not exceeding the limits specified in Column 4 of Table 2.2.7.2.4.1.2 may be

classified under UN 3507 URANIUM HEXAFLUORIDE, RADIOACTIVE MATERIAL,

EXCEPTED PACKAGE, less than 0.1 kg per package, non-fissile or fissile-excepted provided that:

(a) The mass of uranium hexafluoride in the package is less than 0.1 kg;

(b) The conditions of 2.2.7.2.4.5.2 and 2.2.7.2.4.1.4 (a) and (b) are met.

2.2.7.2.4.1.6

Articles manufactured of natural uranium, depleted uranium or natural thorium and articles in which

the sole radioactive material is unirradiated natural uranium, unirradiated depleted uranium or

unirradiated natural thorium may be classified under UN No. 2909 RADIOACTIVE MATERIAL,

EXCEPTED PACKAGE - ARTICLES MANUFACTURED FROM NATURAL URANIUM or

DEPLETED URANIUM or NATURAL THORIUM, provided that the outer surface of the uranium or

thorium is enclosed in an inactive sheath made of metal or some other substantial material.

2.2.7.2.4.1.7

An empty packaging which had previously contained radioactive material may be classified under UN

No. 2908 RADIOACTIVE MATERIAL, EXCEPTED PACKAGE - EMPTY PACKAGING,

provided that:

(a) It is in a well-maintained condition and securely closed;

(b) The outer surface of any uranium or thorium in its structure is covered with an inactive sheath

made of metal or some other substantial material;

exceed:

(i) 400 Bq/cm2 for beta and gamma emitters and low toxicity alpha emitters; and

(ii) 40 Bq/cm2 for all other alpha emitters; and

(d) Any labels which may have been displayed on it in conformity with 5.2.2.1.11.1 are no longer

visible.

2.2.7.2.4.2

Classification as Low specific activity (LSA) material

Radioactive material may only be classified as LSA material if the definition of LSA in 2.2.7.1.3 and

the conditions of 2.2.7.2.3.1, 4.1.9.2 and 7.5.11 CV33 (2) are met.

2.2.7.2.4.3

Classification as Surface contaminated object (SCO)

Radioactive material may be classified as SCO if the definition of SCO in 2.2.7.1.3 and the conditions

of 2.2.7.2.3.2, 4.1.9.2 and 7.5.11 CV33 (2) are met.

2.2.7.2.4.4

Classification as Type A package

Packages containing radioactive material may be classified as Type A packages provided that the

following conditions are met:

Type A packages shall not contain activities greater than either of the following:

(a) For special form radioactive material - A1;

(b) For all other radioactive material - A2.

For mixtures of radionuclides whose identities and respective activities are known, the following

condition shall apply to the radioactive contents of a Type A package:

where B(i) is the activity of radionuclide i as special form radioactive material;

A1(i) is the A1 value for radionuclide i;

C(j) is the activity of radionuclide j as other than special form radioactive material;

A2(j) is the A2 value for radionuclide j.

2.2.7.2.4.5

Classification of uranium hexafluoride

2.2.7.2.4.5.1

Uranium hexafluoride shall only be assigned to:

(a) UN No. 2977, RADIOACTIVE MATERIAL, URANIUM HEXAFLUORIDE, FISSILE;

(b) UN No. 2978, RADIOACTIVE MATERIAL, URANIUM HEXAFLUORIDE, non-fissile or

fissile-excepted; or

PACKAGE less than 0.1 kg per package, non-fissile or fissile-excepted.

2.2.7.2.4.5.2

The contents of a package containing uranium hexafluoride shall comply with the following

requirements:

(a) For UN Nos. 2977 and 2978, the mass of uranium hexafluoride shall not be different from that

allowed for the package design, and for UN No. 3507, the mass of uranium hexafluoride shall

be less than 0.1 kg;

(b) The mass of uranium hexafluoride shall not be greater than a value that would lead to an ullage
