Potential exposure of airplane passengers to doses in excess of statutory limits for the public due to a damaged type A package

On 22 November 2012, a type A package containing Cs-137 (54 GBq) triggered a radiation alarm at the Frankfurt airport, Germany. The package originated in Brisbane, Australia and was shipped on a passenger airplane via Dubai. The package examination found that one of the Cs-137 sources (18.5 GBq) transported in the package was found outside its shielded container but within the overpack and another source was lodged between the lid and body of the shielded container. The maximum dose rate on surface of the overpack was measured to be 33 mSv/hr and 0.94 mSv/hr at distance of 1m.
