Label category 1
WHITE-I.
YELLOW-II.

YELLOW-III.

YELLOW-III (Must be shipped under
exclusive
use
provisions;
see
173.441(b) of this subchapter).

1 Any package containing a  - highway route controlled quantity -  (Section 173.403 of this subchapter) must be labelled as RADIOACTIVE YELLOW-III.
2 If the measured TI is not greater than 0.05, the value may be considered to be zero.

(d) EMPTY label. See Section 173.428(e) of
this subchapter for EMPTY labeling requirements.
(e) FISSILE label. For packages required in Section 172.402 to bear a FISSILE
label, each such label must be completed with the criticality safety index
(CSI) assigned in the NRC or DOE
package design approval, or in the certificate of approval for special arrangement or the certificate of approval for
the package design issued by the Competent Authority for import and export
shipments. For overpacks and freight
containers required in Section 172.402 to bear
a FISSILE label, the CSI on the label
must be the sum of the CSIs for all of
the packages contained in the overpack or freight container.
(f) Each package required by this section to be labeled with a RADIOACTIVE label must have two of these
labels, affixed to opposite sides of the
package. (See Section 172.406(e)(3) for freight
container label requirements).
(g) The following applicable items of
information must be entered in the
blank spaces on the RADIOACTIVE
label by legible printing (manual or
mechanical), using a durable weather
resistant means of marking:
(1) Contents. Except for LSA-1 material, the names of the radionuclides as
taken from the listing of radionuclides
in Section 173.435 of this subchapter (symbols
which conform to established radiation
protection terminology are authorized,
i.e., 99Mo, 60Co, etc.). For mixtures of
radionuclides, with consideration of
space available on the label, the radionuclides that must be shown must be
determined
in
accordance
with
Section 173.433(g) of this subchapter. For LSAI material, the term  - LSA-I -  may be

used in place of the names of the radionuclides.
(2) Activity. The maximum activity of
the radioactive contents in the package during transport must be expressed
in appropriate SI units (e.g., Becquerels
(Bq), Terabecquerels (TBq)). The activity may also be stated in appropriate
customary units (e.g., Curies (Ci),
milliCuries (mCi), microCuries (uCi))
in parentheses following the SI units.
Abbreviations are authorized. Except
for plutonium-239 and plutonium-241,
the weight in grams or kilograms of
fissile radionuclides (or the mass of
each fissile nuclide for mixtures when
appropriate) may be inserted instead of
activity units. For plutonium-239 and
plutonium-241, the weight in grams of
fissile radionuclides (or the mass of
each fissile nuclide for mixtures when
appropriate) may be inserted in addition to the activity units.
(3) Transport index. (see Section 173.403 of
this subchapter.)
(h) When one or more packages of
Class 7 (radioactive) material are
placed within an overpack, the overpack must be labeled as prescribed in
this section, except as follows:
(1) The  - contents -  entry on the label
may state  - mixed -  in place of the
names of the radionuclides unless each
inside package contains the same
radionuclide(s).
(2) The  - activity -  entry on the label
must be determined by adding together
the number of becquerels of the Class 7
(radioactive) materials packages contained therein.
(3) For an overpack, the transport
index (TI) must be determined by adding together the transport indices of
the Class 7 (radioactive) materials
