EAN request on radiation protection of aircraft crew - Final - 7th February 2012 !" " " Results of the EAN request on radiation protection of aircraft crew December 2010 - January 2012 Final document - 7th February 2012 Written by: François Drouet and Marie Michelet Questions sent to the members of the Network: 1. Is there a regulation concerning radiation protection requirements for aircraft crew in your country? 2. If yes: - What are the main requirements? - What are the means and tools used to assess aircrew's exposure? - Is there a specific dose criteria defined for aircraft crew? 3. Could you provide data on the number of aircrew exposed, maximum annual level of exposure, average annual level of exposure, etc.? " EAN request on radiation protection of aircraft crew - Final - 7th February 2012 #" SYNTHESIS 1. Countries answering the request 14 countries answered the request about radiation protection of aircraft crew: Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Ireland, Italy, Lithuania, Slovenia, Sweden, the Netherlands and the UK. There is not a regulation concerning radiation protection requirements for aircraft crew in Norway. 2. Regulations The regulations on radiation protection of aircraft crew are national regulations for every country answering the survey except for Sweden, which has implemented the international recommendations JAR-OPS 1. For most regulations, the main requirements are the following, for exposure higher than 1 mSv a year: - Assess exposure of the crew - Take into account the assessed exposure when organizing flight schedules - Inform the workers on risk due to cosmic radiation - Limit the exposure of pregnant workers Some countries add several requirements such as monitoring (Finland, France), medical surveillance (France). Specific requirements (protection actions) are implemented for exposure higher than 6 mSv.y-1 in Belgium, Denmark, Finland, Germany, Ireland, Lithuania, Slovenia and Greece. In Slovenia a dose constraint of 2 mSv.y-1 is implemented. Furthermore, in Italy and in the Netherlands, aircrew flying regularly over 8 000 m (exposure higher than 1 mSv.y-1 are category B workers). 3. Data The Figure 1 below presents the data concerning the number of aircraft crew exposed and the $%&'()"# the associated annual effective dose (both average and maximum) when available. The number of aircrew exposed varies from 213 in Lithuania to about 40,000 in Germany and the UK. Concerning the maximum annual effective dose, the highest dose are about 6 to 8 mSv for Denmark, Germany and Finland and the lowest is about 1.7 mSv in Slovenia. The average annual effective dose varies from 1 mSv for Czech Republic to 2.5 mSv for both Finland and Sweden.
