mechanical shocks. The vehicle, tie-down system, and auxiliary equipment may be designated as part of the packaging.
Regulations of the U.S. Department of Transportationthe regulations in 49 CFR Parts 100189.
Special Form Radioactive Materialradioactive material that satisfies the following conditions:
a.it is either a single solid piece or is contained in a sealed capsule that can be opened only by destroying the capsule;
b.the piece or capsule has at least one dimension not less than 5 millimeters (0.197 inch); and
c.it satisfies the test requirements of 10 CFR 71.75. A special form encapsulation designed in accordance with the requirements of 10 CFR 71.4 in effect on June 30, 1983 (see 10 CFR Part 71, revised as of January 1, 1983), and constructed prior to July 1, 1985, and a special form encapsulation designed in accordance with the requirements of 10 CFR 71.4 in effect on March 31, 1996 (see 10 CFR Part 71, revised as of January 1, 1983), and constructed before April 1, 1998, may continue to be used. Any other special form encapsulation must meet the specifications of this definition.
Specific Activity of a Radionuclidethe radioactivity of the radionuclide per unit mass of that nuclide. The specific activity of a material in which the radionuclide is essentially uniformly distributed is the radioactivity per unit mass of the material.
Spent Nuclear Fuel or Spent Fuelfuel that has been withdrawn from a nuclear reactor following irradiation, has undergone at least one year's decay since being used as a source of energy in a power reactor, and has not been chemically separated into its constituent elements by reprocessing. Spent fuel includes the special nuclear material, byproduct material, source material, and other radioactive materials associated with fuel assemblies.
Statea State of the United States, or the District of Columbia, the Commonwealth of Puerto Rico, the Virgin Islands, Guam, American Samoa, or the Commonwealth of the Northern Mariana Islands.
Surface Contaminated Object (SCO)a solid object that is not itself classed as radioactive material, but which has radioactive material distributed on any of its surfaces. SCOs must be in one of two groups with surface activity not exceeding the following limits:
a.SCO-I. A solid object on which:
i.the non-fixed contamination on the accessible surface averaged over 300 cm2 (or the area of the surface if less than 300 cm2) does not exceed 4 Bq/cm2 (10-4 microcurie/cm2) for beta and gamma and low toxicity alpha emitters, or 0.4 Bq/cm2 (10-5 microcurie/cm2) for all other alpha emitters;
ii.the fixed contamination on the accessible surface averaged over 300 cm2 (or the area of the surface if less than 300 cm2) does not exceed 4x104 Bq/cm2 (1.0 microcurie/cm2) for beta and gamma and low toxicity alpha emitters, or 4x103 Bq/cm2 (0.1 microcurie/cm2) for all other alpha emitters; and
iii.the non-fixed contamination plus the fixed contamination on the inaccessible surface averaged over 300 cm2 (or the area of the surface if less than 300 cm2) does not exceed 4x104 Bq/cm2 (1 microcurie/cm2) for beta and
gamma and low toxicity alpha emitters, or 4x103 Bq/cm2 (0.1 microcurie/cm2) for all other alpha emitters.
b.SCO-II. A solid object on which the limits for SCO-I are exceeded and on which:
i.the non-fixed contamination on the accessible surface averaged over 300 cm2 (or the area of the surface if less than 300 cm2) does not exceed 400 Bq/cm2 (10-2 microcurie/cm2) for beta and gamma and low toxicity alpha emitters or 40 Bq/cm2 (10-3 microcurie/cm2) for all other alpha emitters;
ii.the fixed contamination on the accessible surface averaged over 300 cm2 (or the area of the surface if less than 300 cm2) does not exceed 8×105 Bq/cm2 (20 microcuries/cm2) for beta and gamma and low toxicity alpha emitters or 8×104 Bq/cm2 (2 microcuries/cm2) for all other alpha emitters; and
iii.the non-fixed contamination plus the fixed contamination on the inaccessible surface averaged over 300 cm2 (or the area of the surface if less than 300 cm2) does not exceed 8×105 Bq/cm2 (20 microcuries/cm2) for beta and gamma and low toxicity alpha emitters, or 8×104 Bq/cm2 (2 microcuries/cm2) for all other alpha emitters.
Transport Indexthe dimensionless number (rounded up to the first decimal place) placed on the label of a package to designate the degree of control to be exercised by the carrier during transportation. The transport index is the number determined by multiplying the maximum radiation level in millisievert (mSv) per hour at 1 meter (3.3 ft) from the external surface of the package by 100, and is equivalent to the maximum radiation level in millirem per hour at 1 meter (3.3 ft).
Type A Quantitya quantity of radioactive material, the aggregate radioactivity of which does not exceed A1 for special form radioactive material, or A2, for normal form radioactive material, where A1 and A2 are given in Table A-1 of 10 CFR Part 71, Appendix A, incorporated by reference in LAC 33:XV.1599.A, or may be determined by procedures described in LAC 33:XV.1599.E.
Type B Quantitya quantity of radioactive material greater than a Type A quantity.
Unirradiated Uraniumuranium containing not more than 2 x 103 Bq of plutonium per gram of uranium-235, not more than 9 x 106 Bq of fission products per gram of uranium-235, and not more than 5 x 10-3 grams of uranium-236 per gram of uranium-235.
Uranium: Natural, Depleted, Enriched
a.Natural Uraniumuranium with the naturally occurring distribution of uranium isotopes (approximately 0.711 weight percent uranium-235, and the remainder by weight essentially uranium-238).
b.Depleted Uraniumuranium containing less uranium-235 than the naturally occurring distribution of uranium isotopes.
c.Enriched Uraniumuranium containing more uranium-235 than the naturally occurring distribution of uranium isotopes.
