30 AFMAN 24-204(I)/TM 38-250/NAVSUP PUB 505/MCO P4030.19H/ DLAI 4145.3 11 DECEMBER 2001 - For fissile class II packages or packages in a fissile class III shipment, the number expressing the maximum radiation level at one meter (3.3 feet) from the external surface of the package, or the number obtained by dividing 50 by the allowable number of packages that may be transported together, whichever is larger. Type A Package--A type A packaging (see definition for type A packaging) together with its limited radioactive contents. A type A package does not require competent authority approval since its contents are limited to A₁ or ^A2^. Type A Packaging--A packaging designed to retain the integrity of containment and shielding required by this manual under normal conditions of transport, as demonstrated by the tests set forth in 49 CFR 173.465 or 173.466. Type B (M) Package--A type B packaging (see definition for type B packaging), together with its radioactive contents, that for international shipments requires multilateral approval of the package design and may require approval of the conditions of shipment. Type B(M) packages are those type B package designs that have a maximum normal operating pressure of more than 7 kg/cm² (100 pounds/in²gauge) or a relief device that allows the release of radioactive material to the environment under the hypothetical accident conditions specified in 10 CFR, part 71. Type B (U) Package--A type B packaging (see definition for type B packaging), together with its radioactive contents, that for international shipments requires unilateral approval only of the package design and of any stowage provisions that may be necessary for heat dissipation. Type B Package--A type B packaging (see definition for type B packaging) together with its radioactive contents. Type B Packaging--Is a packaging designed to retain the integrity of containment and shielding required when subjected to the normal conditions of transport and hypothetical accident test conditions set forth in 10 CFR, part 71. Uncompressed Gas--For the purposes of this manual, gas at a pressure not exceeding the ambient atmospheric pressure at the time and location the containment system is closed. All other radioactive gases are considered to be compressed. Unirradiated Thorium--Thorium containing not more than 10^-7 grams uranium²³³per gram of thorium²³². Unirradiated Uranium--Uranium containing not more than 10^-6grams plutonium per gram of uranium²³⁵ and a fission product activity of not more than 0.25 mCi of fission products per gram of uranium²³⁵. Wetted Explosive--This material, when dry, is a Class 1 material other than those of compatibility group A. Items in compatibility group A have been wetted with sufficient water, alcohol, or plasticizer to suppress explosive properties. Wetted explosives also includes items specifically authorized by name in table A4.1 or which have been assigned a PSN and hazard class by the DOT.
