10.5.11.1 Activity Limits
Type B(U) and Type B(M) must in addition not contain activities greater than the following:
(a)for low dispersible radioactive material, as authorized for the package design as specified in the certificate of approval;
(b)for Special Form radioactive material, 3,000 A1 or 100,000 A2, whichever is the lower; or
(c)for all other radioactive material, 3,000 A2.
10.5.11.2 Unilateral Approval
Each Type B(U) package design requires unilateral approval, i.e. approval of the competent authority of the State of origin of design only, except that
(a)a Type B(U) package design for fissile material, which is also subject to 10.5.11.3 and 10.5.7.2.2, must require multilateral approval; and
(b)a Type B(U) package design for low dispersible radioactive material must require multilateral approval.
10.5.11.3 Multilateral Approval
Each Type B(M) package design requires multilateral approval, i.e. approval by the competent authorities of the State of origin and of each State through or into which the package is to be transported (see Note following definition of “Multilateral Approval” in Appendix A).
Note:
Type B(M) packages are forbidden on Passenger Aircraft.
10.5.12 Type C Packages
Type C packages may contain activities greater than A1 (if Special Form radioactive material) or A2 (if not in Special Form radioactive material). Type C packages must be designed to meet the requirements of 10.6.0, 10.6.1, 10.6.2.4.1 except for 10.6.2.4.1(b), 10.6.2.4.2, 10.6.2.5.3, 10.6.2.5.4, 10.6.2.5.6, 10.6.2.5.11 to 10.6.2.5.16, and, in addition, the requirements specified in
10.6.2.7.3 to 10.6.2.7.5.

10.5.13.1 Fissile Material Activity Limit
Unless excepted by 10.3.7.2, any packages containing fissile material must not contain:
(a)a mass of fissile material (or mass of each fissile nuclide for mixtures when appropriate) different than that authorized for the package design;
(b)any radionuclide or fissile material different from those authorized for the package design; or
(c)contents in a form or physical or chemical state, or in a spatial arrangement, different from those author-ized for the package design;
as specified in the certificate of approval where appropriate.
10.5.13.2 Design
The design for packaging for fissile material must comply in all respects with the requirements for packages con-taining fissile materials of 10.3.7 and 10.6.2.8.
10.5.13.3 Approval
Each package design for fissile material requires multilat-eral approval, i.e. approval by the competent authorities of the State of origin and of each State through or into which the package is to be transported.
10.5.14 Determination of Transport Index and Criticality Safety Index
STATE VARIATIONS: JPG02/17, USG10
OPERATOR VARIATIONS: 8X01, TX01
10.5.14.1 Determination of Transport Index (TI)
Transport Index (TI) is a single number assigned to a package, overpack or freight container used to provide control over radiation exposure. It is also used to estab-lish categories for labelling, to determine whether trans-port under exclusive use is required; to establish spacing requirements during storage in transit, and to define the number of packages allowed in a freight container or aboard an aircraft. The TI is determined as described in
10.5.14.1.1 and 10.5.14.1.2.
10.5.14.1.1 Transport Index—RadiationExposure Control
The TI based on radiation exposure control for a pack-age, overpack or freight container is the number derived using the following procedure:
(a)  determine the maximum radiation level at a distance of 1 m from the external surfaces of the package, overpack or freight container. Where the radiation level is determined in units of millisievert per hour (mSv/h), the value determined must be multiplied by
