Infected animals

Unless an infectious substance cannot be consigned by any other means, live animals shall not be used
to consign such a substance. A live animal which has been intentionally infected and is known or
suspected to contain an infectious substance shall only be carried under terms and conditions
approved by the competent authority.
NOTE: The approval of the competent authorities shall be issued on the basis of the relevant rules
for the carriage of live animals, taking into consideration dangerous goods aspects. The authorities
that are competent to lay down these conditions and rules for approval shall be regulated at national
level.
If there is no approval by a competent authority of a Contracting Party to ADR, the competent
authority of a Contracting Party to ADR may recognize an approval issued by the competent authority
of a country that is not a Contracting Party to ADR.
Rules for the carriage of livestock are, for example, contained in Council Regulation (EC) No 1/2005
of 22 December 2004 on the protection of animals during transport (Official Journal of the European
Union No L 3 of 5 January 2005) as amended.

 

Animal material affected by pathogens of Category A or by pathogens which would be assigned to
Category A in cultures only, shall be assigned to UN 2814 or UN 2900 as appropriate. Animal
material affected by pathogens of Category B, other than those which would be assigned to Category
A if they were in cultures, shall be assigned to UN 3373.

List of collective entries

Live vertebrate or invertebrate animals shall not be used to carry an infectious agent unless the agent
cannot be carried by other means or unless this carriage has been approved by the competent authority
(see 2.2.62.1.12.1).

Class 7 Radioactive material

Definitions

Radioactive material means any material containing radionuclides where both the activity
concentration and the total activity in the consignment exceed the values specified in 2.2.7.2.2.1 to
2.2.7.2.2.6.

Contamination

Contamination means the presence of a radioactive substance on a surface in quantities in excess of
0.4 Bq/cm2 for beta and gamma emitters and low toxicity alpha emitters, or 0.04 Bq/cm2 for all other
alpha emitters.
Non-fixed contamination means contamination that can be removed from a surface during routine
conditions of carriage.
Fixed contamination means contamination other than non-fixed contamination.

Definitions of specific terms

A1 and A2
A1 means the activity value of special form radioactive material which is listed in the Table in
2.2.7.2.2.1 or derived in 2.2.7.2.2.2 and is used to determine the activity limits for the
requirements of ADR.
A2 means the activity value of radioactive material, other than special form radioactive
material, which is listed in the Table in 2.2.7.2.2.1 or derived in 2.2.7.2.2.2 and is used to
determine the activity limits for the requirements of ADR.
Fissile nuclides means uranium-233, uranium-235, plutonium-239 and plutonium-241. Fissile
material means a material containing any of the fissile nuclides. Excluded from the definition of
fissile material are the following:
(a) Natural uranium or depleted uranium which is unirradiated;
(b) Natural uranium or depleted uranium which has been irradiated in thermal reactors only;
(c) Material with fissile nuclides less than a total of 0.25 g;
(d) Any combination of (a), (b) and/or (c).
These exclusions are only valid if there is no other material with fissile nuclides in the package or in
the consignment if shipped unpackaged.
Low dispersible radioactive material means either a solid radioactive material or a solid radioactive
material in a sealed capsule, that has limited dispersibility and is not in powder form.
Low specific activity (LSA) material means radioactive material which by its nature has a limited
specific activity, or radioactive material for which limits of estimated average specific activity apply.
External shielding materials surrounding the LSA material shall not be considered in determining the
estimated average specific activity.
Low toxicity alpha emitters are: natural uranium; depleted uranium; natural thorium; uranium-235 or
uranium-238; thorium-232; thorium-228 and thorium-230 when contained in ores or physical and
chemical concentrates; or alpha emitters with a half-life of less than 10 days.
Special form radioactive material means either:
(a) An indispersible solid radioactive material; or
(b) A sealed capsule containing radioactive material.
Specific activity of a radionuclide means the activity per unit mass of that nuclide. The specific
activity of a material shall mean the activity per unit mass of the material in which the radionuclides
are essentially uniformly distributed.
Surface contaminated object (SCO) means a solid object which is not itself radioactive but which has
radioactive material distributed on its surface.
Unirradiated thorium means thorium containing not more than 10-7 g of uranium-233 per gram of
thorium-232.
Unirradiated uranium means uranium containing not more than 2 × 103 Bq of plutonium per gram of
uranium-235, not more than 9 × 106 Bq of fission products per gram of uranium-235 and not more
than 5 × 10-3 g of uranium-236 per gram of uranium-235.
Uranium - natural, depleted, enriched means the following:
Natural uranium means uranium (which may be chemically separated) containing the naturally
occurring distribution of uranium isotopes (approximately 99.28% uranium-238, and 0.72%
uranium-235 by mass).
Depleted uranium means uranium containing a lesser mass percentage of uranium-235 than in
natural uranium.
Enriched uranium means uranium containing a greater mass percentage of uranium-235
than 0.72%.
In all cases, a very small mass percentage of uranium-234 is present.

 

Classification

General provisions

Radioactive material shall be assigned to one of the UN numbers specified in Table 2.2.7.2.1.1, in
accordance with 2.2.7.2.4 and 2.2.7.2.5, taking into account the material characteristics determined in
2.2.7.2.3.
