There exists a considerable variation in the approaches of European countries to the radiation protection education and vocational training arrangements for radiation protection. Furthermore, there exists diversity in the qualifications and diplomas necessary for the recognition of radiation protection experts as defined by the European Union's Basic Safety Standards Directive 96/29/Euratom. This diversity creates an obstruction to the mobility of radiation protection experts in the EU. However, the freedom of movement between member states of persons and services constitutes one of the objectives of the EU. This implies the possibility of pursuing a profession in a member state other than the one where these persons have acquired their professional qualifications.
