[Code of Federal Regulations] [Title 49, Volume 2] [Revised as of October 1, 2007] From the U.S. Government Printing Office via GPO Access [CITE: 49CFR172.403] [Page 382-384] TITLE 49--TRANSPORTATION CHAPTER I--PIPELINE AND HAZARDOUS MATERIALS SAFETY ADMINISTRATION, DEPARTMENT OF TRANSPORTATION PART 172_HAZARDOUS MATERIALS TABLE, SPECIAL PROVISIONS, HAZARDOUS MATERIALS COMMUNICATIONS, EMERGENCY RESPONSE INFORMATION, AND 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: [[Page 383]] ------------------------------------------------------------------------ Maximum radiation level at any point Transport index on the external Label category \1\ surface ------------------------------------------------------------------------ 0\2\.......................... Less than or equal WHITE-I. 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) FISSILE label. For packages required in Sec. 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 Sec. 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 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. Except for LSA-1 material, the names 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(g) of this subchapter. For LSA-I material, the term ``LSA-I'' may be used in place of the names of the radionuclides. (2) Activity. The activity in the package must be expressed in appropriate SI units (e.g., Becquerels (Bq), Terabecquerels (TBq), etc.). The activity may also be stated in appropriate customary units (Curies (Ci), milliCuries (mCi), microCuries (uCi), etc.) 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 may be inserted instead of activity units. For plutonium-239 and plutonium-241, the weight in grams of fissile radionuclides may be inserted in addition to the activity units. (3) Transport index. (see Sec. 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 packages contained therein, except that for a rigid overpack, the transport [[Page 384]] index (TI) may alternatively be determined by direct measurement as prescribed in Sec. 173.403 of this subchapter under the definition for ``transport index,'' taken by the person initially offering the packages contained within the overpack for shipment. (4) The category of Class 7 label for the overpack must be determined from the table in Sec. 172.403(c) using the TI derived according to paragraph (h)(3) of this section, and the maximum radiation level on the surface of the overpack. (5) The category of the Class 7 label of the overpack, and not that of any of the packages contained therein, must be used in accordance with Table 1 of Sec. 172.504(e) to determine when the transport vehicle must be placarded. (6) For fissile material, the criticality safety index which must be entered on the overpack FISSILE label is the sum of the criticality safety indices of the individual packages in the overpack, as stated in the certificate of approval for the package design issued by the NRC or the U.S. Competent Authority.
