The Institute for the Protection and Security of the Citizen provides researchbased, systemsorientedsupport to EU policies so as to protect the citizen against economic and technologicalrisk. The Institute maintains and develops its expertise and networks in information,communication, space and engineering technologies in support of its mission. The strongcrossfertilisation between its nuclear and non-nuclear activities strengthens the expertise it canbring to the benefit of customers in both domains.European CommissionJoint Research CentreInstitute for the Protection and Security of the CitizenContact informationAddress: Fabio TAUCERE-mail: fabio.taucer@jrc.itTel.: +39 0332 78.5886Fax: +39 0332 78.9049http://ipsc.jrc.ec.europa.euhttp://www.jrc.ec.europa.euLegal NoticeNeither the European Commission nor any person acting on behalf of the Commission isresponsible for the use which might be made of this publication.A great deal of additional information on the European Union is available on the Internet.It can be accessed through the Europa serverhttp://europa.eu/JRC38009EUR 22885 ENISSN 1018-5593Luxembourg: Office for Official Publications of the European Communities© European Communities, 2007Reproduction is authorised provided the source is acknowledgedPrinted in Italy
