A European post-graduate training course leading to the degree of Master of Science in Radiation Biology will be held in the academic year 1994/1995 at London University. The European dimension of this course will be assured by the European Commission's sponsorship of three or four students from Member States other than the UK and by approximately 150 hours teaching by eminent European lecturers. In a common approach, the Commission's European Radiation Protection Education and Training Action (ERPET) and St. Bartholomew's Medical College of the University of London have adapted the existing MSc course in Radiation Biology to reflect the most up-to-date European expertise in all aspects of this science. Post-graduate students who wish to apply for the course and the Commission-ERPET studentship should be citizens of a Member State other than the UK and have graduated with a good degree from a University of the Member State. They should be fluent in written and spoken English. The application should include a curriculum vitae, a copy of the University degree certificate, names and addresses of two referees, if possible those University teachers who supervised the student during the last year of undergraduate studies, and a statement about his capacity to understand and speak English. The ERPET-sponsored studentship covers University fees and living expenses for one academic year totalling ECU 10,000 and will be awarded in open competition by the ERPET Training Committee.
