11 DECEMBER 2001
-
A package containing any fissile material if it does not contain more than 5 grams of fissile
radionuclides in any 10 liter volume, and if the material is packaged to maintain this limit of fissile
radionuclide concentration during normal transport.
-
A package containing not more than one kg of plutonium of which not more than 20 percent by mass
may consist of plutonium239, plutonium241, or any combination of those radionuclides.
-
A package containing liquid solutions of uranyl nitrate enriched in uranium235 to a maximum of 2
percent by weight, with total plutonium and uranium233 not more than 0.1 percent of the mass of
uranium235.
-
A package containing thorium or uranium with not more than 0.72 percent by weight of fissile material
used for shipment solely within the United States.
A3.3.7.10. Requirements for Foreign-Made Packages. In addition to the requirements of attachment 11, each
shipper of a foreign-made type B, type B(U), type B(M) or fissile material package for which a competent authority
certificate is required by the IAEA "Regulations for the Safe Transport of Radioactive Materials, Safety Series No.
6" or the IAEA "Regulations for the Safe Transport of Radioactive Materials, No. TS-R-1” must meet the
requirements of 49 CFR 173.473.
A3.3.7.11. Radioactive Contamination.
-
Contamination Control. Keep the level of nonfixed (removable) radioactive contamination on the
external surfaces of each package offered for shipment as low as practical. The level of nonfixed
radioactive contamination may be determined by wiping an area of 300 cm2 of the surface concerned with
an absorbent material, using moderate pressure, and measuring the activity on the wiping material. Take
sufficient measurements in the most appropriate locations to yield a representative assessment of the
nonfixed contamination levels. The amount of radioactivity measured on any single wiping material, when
averaged over the surface wiped, must not exceed the limits given in table A3.3 at any time during
transport. Other methods of assessment of equal or greater efficiency may be used. When other methods
are used, take the detection efficiency of the method used into account and in no case must the nonfixed
contamination on the external surfaces of the package exceed 10 times the limits listed in table A3.3.
-
Inspecting Aircraft for Contamination. Periodically check aircraft used to routinely transport radioactive
materials for radioactive contamination. Determine frequency of the checks based on the likelihood of
contamination and the extent to which radioactive materials are carried aboard the aircraft. An aircraft
must be taken out of service if the radiation dose rate at any accessible surface is 0.005 mSv/h (0.5 mrem/h)
or if there is significant removable radioactive surface contamination as outlined above.

A3.3.8. Class 8.
-
Packed with Other Materials. Do not pack bottles containing corrosive liquids in the same outside
container with other hazardous materials.
-
Packaging. Unless otherwise specified by a packaging paragraph, package a liquid material identified as
PG III in table A4.1 in a container that meets the PG I or II performance level.
A3.3.9. Class 9. Any package that has a magnetic field strength of more than 0.00525 gauss measured at 4.6 m (15
ft) from any surface of the package is forbidden on military aircraft.
