Classification as excepted package

A package may be classified as an excepted package if it meets one of the following conditions:
(a) It is an empty package having contained radioactive material;
(b) It contains instruments or articles not exceeding the activity limits specified in columns (2) and
(3) of Table 2.2.7.2.4.1.2;
(c) It contains articles manufactured of natural uranium, depleted uranium or natural thorium;
(d) It contains radioactive material not exceeding the activity limits specified in column (4) of
Table 2.2.7.2.4.1.2; or
(e) It contains less than 0.1 kg of uranium hexafluoride not exceeding the activity limits specified
in column (4) of Table 2.2.7.2.4.1.2.

A package containing radioactive material may be classified as an excepted package provided that the
radiation level at any point on its external surface does not exceed 5 μSv/h.

Radioactive material which is enclosed in or is included as a component part of an instrument or other
manufactured article may be classified under UN No. 2911 RADIOACTIVE MATERIAL,
EXCEPTED PACKAGE - INSTRUMENTS or ARTICLES provided that:
(a) The radiation level at 10 cm from any point on the external surface of any unpackaged
instrument or article is not greater than 0.1 mSv/h;
(b) Each instrument or manufactured article bears the mark "RADIOACTIVE" on its external
surface except for the following:
(i) radioluminescent time-pieces or devices;
(ii) consumer products that have either received regulatory approval in accordance with
1.7.1.4 (e) or do not individually exceed the activity limit for an exempt consignment in
Table 2.2.7.2.2.1 (column 5), provided such products are transported in a package that
bears the mark "RADIOACTIVE" on its internal surface in such a manner that a
warning of the presence of radioactive material is visible on opening the package; and
(iii) other instruments or articles too small to bear the mark "RADIOACTIVE", provided
that they are transported in a package that bears the mark "RADIOACTIVE" on its
internal surface in such a manner that a warning of the presence of radioactive material
is visible on opening the package;
(c) 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); and
(d) The limits specified in columns 2 and 3 of Table 2.2.7.2.4.1.2 are met for each individual item
and each package, respectively.

Radioactive material in forms other than as specified in 2.2.7.2.4.1.3 and with an activity not
exceeding the limits specified in column 4 of Table 2.2.7.2.4.1.2, may be classified under UN No.
2910 RADIOACTIVE MATERIAL, EXCEPTED PACKAGE - LIMITED QUANTITY OF
MATERIAL provided that:
(a) The package retains its radioactive contents under routine conditions of carriage; and
(b) The package bears the mark "RADIOACTIVE" on either:
(i) An internal surface in such a manner that a warning of the presence of radioactive
material is visible on opening the package; or
(ii) The outside of the package, where it is impractical to mark an internal surface.

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.

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.

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;
(c) The level of internal non-fixed contamination, when averaged over any 300 cm2, does not
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.

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.

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.

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.
 
 

Classification of uranium hexafluoride

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.

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
smaller than 5% at the maximum temperature of the package as specified for the plant systems
where the package shall be used; and
(c) The uranium hexafluoride shall be in solid form and the internal pressure shall not be above
atmospheric pressure when presented for carriage.

Classification as Type B(U), Type B(M) or Type C packages
