4. The date 14 March 2006 had marked the fiftieth anniversary of the first session of the Committee. As part of the commemoration of that event, the Government of Japan and the Chairman of the fifty-third session of the Committee, Yasuhito Sasaki, had arranged for publication of all the past reports of the Committee to be made available electronically on its website; the structure, design and content of the website was also generally overhauled. Moreover, during the fifty-fourth session of the Committee, the Mayor and Governor of the City of Vienna hosted a reception for invited dignitaries, scientists and diplomats at the Vienna Town Hall to commemorate the anniversary. On that occasion, the Director-General of the United Nations Office at Vienna delivered a message from the Secretary-General; the special guest speaker was Hans Blix; and other speakers attended from the International Atomic Energy Agency (IAEA), the World Health Organization (WHO) and UNEP. The speakers, especially Hans Blix, highlighted the importance of the Committee’s scientific work over the past 50 years, recognizing its achievements and reputation for scientific independence and credibility. He reflected that, with the important developments in radiation science and major environmental challenges, there was a need to strengthen support for the Committee. The Director and Regional Representative, Regional Office for Europe, of UNEP undertook actively to explore options for enhanced future support. He considered that a more apparent relationship between the scientific appraisals made by the Committee and UNEP-led policy exchanges would facilitate joint efforts to strengthen and broaden the Committee’s resource base.
