                        TITLE 49--TRANSPORTATION
 
 CHAPTER I--RESEARCH AND SPECIAL PROGRAMS ADMINISTRATION, DEPARTMENT OF 
                             TRANSPORTATION
 
                           Subpart E_Labeling
 
Sec.  172.403  Class 7 (radioactive) material.

    (a) Unless excepted from labeling by Sec. Sec.  173.421 through 
173.427 of this subchapter, each package of radioactive material must be 
labeled as provided in this section.
    (b) The proper label to affix to a package of Class 7 (radioactive) 
material is based on the radiation level at the surface of the package 
and the transport index. The proper category of label must be determined 
in accordance with paragraph (c) of this section. The label to be 
applied must be the highest category required for any of the two 
determining conditions for the package. RADIOACTIVE WHITE-I is the 
lowest category and RADIOACTIVE YELLOW-III is the highest. For example, 
a package with a transport index of 0.8 and a maximum surface radiation 
level of 0.6 millisievert (60 millirems) per hour must bear a 
RADIOACTIVE YELLOW-III label.
    (c) Category of label to be applied to Class 7 (radioactive) 
materials packages:

------------------------------------------------------------------------
                                 Maximum radiation
                                 level at any point
        Transport index           on the external      Label category1
                                      surface
------------------------------------------------------------------------

                                 to 0.005 mSv/h
                                 (0.5 mrem/h).
More than 0 but not more than   Greater than 0.005   YELLOW-II.
 1.                              mSv/h (0.5 mrem/h)
                                 but less than or
                                 equal to 0.5 mSv/h
                                 (50 mrem/h).
More than 1 but not more than   Greater than 0.5     YELLOW-III.
 10.                             mSv/h (50 mrem/h)
                                 but less than or
                                 equal to 2 mSv/h
                                 (200 mrem/h).
More than 10..................  Greater than 2 mSv/  YELLOW-III (Must be
                                 h (200 mrem/h) but   shipped under
                                 less than or equal   exclusive use
                                 to 10 mSv/h (1,000   provisions; see
                                 mrem/h).             173.441(b) of this
                                                      subchapter).
------------------------------------------------------------------------
1 Any package containing a ``highway route controlled quantity'' (Sec.
  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 Sec.  173.428(d) of this subchapter for EMPTY 
labeling requirements.
    (e) [Reserved]
    (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 Sec.  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. The name of the radionuclides as taken from the 
listing of radionuclides in Sec.  173.435 of this subchapter (symbols 
which conform to established radiation protection terminology are 
authorized, i.e., \99\Mo, \60\Co, 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 Sec.  
173.433(f) of this subchapter.

[[Page 364]]

    (2) Activity. Activity units must be expressed in appropriate SI 
units (e.g., Becquerels (Bq), Terabecquerels (Tbq), etc.) or in both 
appropriate SI units and appropriate customary units (Curies (Ci), 
MilliCuries (mCi) microCuries (uCi), etc.). Abbreviations are 
authorized. Except for plutonium-238, plutonium-239, and plutonium-241, 
the weight in grams or kilograms of fissile radionuclides may be 
inserted instead of activity units. For plutonium-238, plutonium-239, 
and plutonium-241, the weight in grams or kilograms of fissile 
radionuclides may be inserted in addition to the activity units.
    (3) Transport index. (See Sec.  173.403 of this subchapter.)
