International Civil Aviation Organization
Technical Instructions
The International Civil Aviation Organization (ICAO) has
responsibility for all aspects of international civil aviation. It
develops standards and recommended practices through the
development of Annexes to the 1944 Convention on International
Civil Aviation. In 1981, the ICAO adopted Annex 18 covering the air
transport of dangerous goods and, in addition, published a set of
Technical Instructions detailing the requirements for these
transports. The Technical Instructions contain a list of dangerous
goods, as well as requirements for packing, marking, labelling and
documentation fully consistent with the IAEA Regulations.
The International Air Transport Association (IATA), a trade
association representing airlines, publishes annually the Dangerous
Goods Regulations (DGR) which are consistent with the ICAO
Technical Instructions as well as the IAEA Regulations.
Universal Postal Convention
Transport of radioactive material by post is regulated by the
Universal Postal Convention and its detailed regulations, published
by the Universal Postal Union. The Convention allows the transport
of exempted quantities of radioactive materials, within the meaning
of the IAEA Regulations, and must conform to IAEA
prescriptions.
