Radioactive Material Shipping: IATA and IMDG Class 7 Regulations

Shipping Radioactive Materials Under IATA and IMDG Class 7

Class 7 radioactive materials—used in medical diagnostics, industrial gauges, research, and nuclear applications—require the most stringent shipping controls of any hazard class. South Florida’s medical and industrial sectors ship radioactive materials through certified hazmat channels requiring specialized expertise.

Transport Categories

Radioactive materials are assigned transport categories (I-White, II-Yellow, III-Yellow) based on surface radiation levels and transport index. These categories determine labeling, vehicle placarding, segregation distances from people and undeveloped film, and maximum quantities per conveyance.

Package Types

Radioactive materials ship in four package types based on activity levels: Excepted Packages (very low activity), Type A Packages (low to moderate activity), Type B Packages (high activity requiring impact and fire resistance), and Type C Packages (air transport of high activity requiring extreme impact resistance).

IATA Air Transport Requirements

Air shipping of radioactive materials requires advance notification to the airline, radiation monitoring before and after loading, specific stowage positions away from passengers and crew, and contamination checks of the aircraft after unloading.

IMDG Ocean Transport Provisions

Maritime transport follows similar classification but allows larger quantities with specific stowage requirements. Radioactive cargo must be stowed away from living quarters and regularly occupied spaces. Container stowage positions are strictly regulated.

Medical Radioisotope Shipping

Technetium-99m, Iodine-131, and other medical isotopes used in diagnostic imaging and cancer treatment ship under tight timelines due to short half-lives. South Florida hospitals and imaging centers receive these time-critical shipments through a specialized freight forwarder.

Regulatory Oversight

Radioactive material shipping is overseen by the NRC, DOT, FAA, and Coast Guard. Non-compliance carries severe criminal penalties and license revocation. Only shippers with comprehensive training and proper licensing should handle Class 7 materials.
