We all enjoy the use of Class 7 materials
Throughout our daily life we all have access to and can enjoy benefits derived from the application of radioactive and nuclear materials across the:
health and medical industry
manufacturing, engineering, construction related industries
electric power generation industry
Class 7 is simply one of nine classes of Dangerous Goods
WORLD NUCLEAR TRANSPORT INSTITUTE
3
Framework for the transport of radioactive materials
Governed by a stringent regulatory regime involving standards, codes and regulations
continuously revised and updated over the past five decades
UN adopts the IAEA guidance on the Transport of Dangerous Goods
the IAEA Transport Regulations for RAM apply almost everywhere in the world
a set of recommended regulatory standards covering international transport activities involving RAM
Supplementary guidance documents contain advisory and explanatory material
describing the reason for the regulations, their purpose along with information explaining how to comply with the regulations
Additional guidance documents provide practical advice about
transport management systems and plans and response to transport incidents
development of radiation protection programs, and compliance assurance programmes

Assessment of material to be transported
Material to be transportedISO with drums
Is the material radioactive (above 1Bq/g) YES
Does the 10 times transport exemption apply? NO
Is the consignment an Excepted Package (para. 516)
NO
Total Activity Th232 (and 10 decay products) (Bq/g)
2000.0
Total Activity U (and 14 decay products) (Bq/g) 402.5
Total Activity U and Th plus decay products (Bq/g) 2402.5
TI Multiplication Factor from Table 7 3
Transport Index 11.2
Does the TI of the package call for “exclusive use” YES
Category of package as per table 8III
YELLOW
Description bq/gm ppm U ppm Th
Radioactive material limit 1 80 240
Transport Exemption limit 10 800 2400
Material to be transportedISO with drums
Quantity of material in the package kg 18,000
Largest cross-sectional area of package in square metres
15.74
ppm ThO2 48,000
ppm U 2,300
Max gamma dose rate* at surface (uSv/h) 81.30
Max gamma dose rate* at 1m (uSv/h) 37.40
Material contains natural Uranium and Thorium (YES / NO)
YES
Activity in Th232 decay chain (Bq/g) 200.0
Activity in U238 decay chain (Bq/g) 28.8
Activity in U235 decay chain (Bq/g) 1.15
Weighted avg of U and Th (Head of chain) Bq/g 228.8
Transport exemption (10* factor) 22.88
Is the material LSA-1 (para.409) YES
*The above gamma dose rates have been estimated using first principles based on a 20 foot ISO shipping container having dimensions of 6m x 2.6m x 2.4m loaded with 20 tonnes of material. As such these measurements MUST be confirmed by in field measurements

Detailed manifest information
Comprises detailed drum and batch related information for each shipping container
details in green flow through to summarised delivery and container packing list
manifest also provides radiation dose rate information for each drum
WORLD NUCLEAR TRANSPORT INSTITUTE

Detailed manifest information
Provides a singular overview of the total quantity of RAM packed in each shipping container
information in green flows to the Multimodal DG form, yellow for safeguards transfer
the manifest also provides radiation dose rate information per shipping container

Some examples of container packing
205 litre re-sealable steel drums secured in 20’ ISO containers shipped as full container loads under exclusive use

Inspection of shipping containers pre and post packing
Container inspection is an important process exacerbated by increased focus on Convention for Safe Containers (CSC) compliance
and United States Customs Trade Protection Against Terrorism (C-TPAT) requirements
addresses IMDG multimodal requirements and obligations

Straight forward safeguards and export approval processes
Apply for ASNO safeguards transfer of RAM simple form, by email
Apply for DIS export of strategic commodity simple spreadsheet format, by email
Receive approvals from both parties notification by email
Lodge export declaration with ACS standard customs cargo clearance, lodged electronically
Notify safeguards after vessel departs with cargo on board simple email, then track and monitor through to final destination
safeguards reconciliation following agreement of assay exchange
