Design, construct, and load each package of radioactive material so that:
The heat generated within the package due to the radioactive contents will not, at any time during
transportation, affect the integrity of the package under normal transportation conditions.
The temperature of the accessible external surfaces of the loaded package will not, assuming still air in
the shade at an ambient temperature of 38 degrees C (100 degrees F), exceed either a temperature of 50
degrees C (122 degrees F) in other than an exclusive use shipment or 82 degrees C (180 degrees F) in
an exclusive use shipment.
A188.8.131.52. General Transportation Requirements.
Secure each shipment of radioactive materials to prevent shifting during normal transportation conditions.
Except as specifically required by a CAA, a package of radioactive materials may be carried among
packaged general cargo without special stowage provisions, if:
The heat output in watts is not over 0.1 times the minimum package dimension in centimeters.
The average surface heat flux of the package is not over 15 watts per square meter (W/m2) and the
immediately surrounding cargo is not in sacks or bags or otherwise in a form that would seriously
impede air circulation for heat removal.
Aircraft in which radioactive materials have been spilled may not again be placed in service or routinely
occupied until radiation dose rate at any accessible surface is less than 0.005 mSv/h (0.5 mrem/h) and there
is no significant removable radioactive surface contamination as determined in A184.108.40.206. When
contamination is present or suspected, segregate the package and any other materials it has touched as far
as practical from personnel contact until needed radiological advice or assistance is obtained. For
personnel safety, take care to avoid possible inhalation, ingestion, or contact with radioactive materials that
may have leaked or spilled from its package. Leave any loose radioactive materials and associated
packaging materials in a segregated area pending disposal instructions from responsible radiological
Do not offer for military airlift:
Any type B(U) or type B(M) package with an accessible surface temperature in excess of 50 degrees C
(122 degrees F).
Any continuously vented type B(M) packages, which require external cooling by an auxiliary cooling
system or packages subject to operational controls during transport.
Any liquid pyrophoric radioactive materials.
Do not transport exclusive use shipments of packages having a surface radiation level in excess of 2 mSv/h
(200 mrem/h) except by special arrangement.
A220.127.116.11. Approval of Special Form Radioactive Material.
Each shipper of special form radioactive materials must maintain on file for at least 1 year after the latest
shipment, a complete safety analysis, including documentation of any tests demonstrating that the special
form material meets the requirements of 49 CFR 173.469. An International Atomic Energy Agency
(IAEA) certificate of competent authority issued for the special form material may be used to satisfy this
Before the first export shipment of a special form radioactive material from the United States, each shipper
must obtain a competent authority certificate for the specific material. For special form material
manufactured outside the United States an IAEA certificate of component authority from the country of
origin may be used to meet this requirement. For special form materials manufactured in the United States
each shipper must obtain a US competent authority certificate for the specific material. Submit each
petition for a US competent authority certificate according to 49 CFR 173.471 and include the following
A detailed description of the material or, if a capsule, a detailed description of the contents. Make a
particular reference to both physical and chemical states.
If a capsule is used, a detailed statement of its design and dimensions, including complete engineering
drawings and schedules of material, and methods of construction.
A statement of tests performed and their results; evidence based on calculative methods to show that
the material is able to pass the tests; or other evidence that the special form radioactive material
complies with 49 CFR 173.469.
