Survey of transport of radioactive materials by air to, from and within UK

Abstract Packages containing radioactive materials are transported by air to, from and within the UK, and this paper describes the results of the latest survey of these operations. The majority of the materials being shipped are destined for medical uses. Cargo handlers involved in the handling of radioactive materials at airports were found to receive annual exposures of up to some 2 mSv. Aircrew members on the flight deck and in cabin areas are estimated to receive annual doses below 0·2 mSv from such packages. On passenger aircraft, packages of radioactive materials are generally carried daily on the same routes and at the same times. There was no evidence of a passenger routinely flying on the same flight as radioactive cargo. However, using the most conservative assumptions of such routine travel, this would result in a potential annual dose of around 0·2 mSv.
