Press release

New nuclear reactors built around the world

One of the major ASN concerns is to achieve harmonization based on the best nuclear safety and radiation protection levels worldwide. We do not want a “two-speed” safety and we continue to promote at European and international levels safety objectives that take into account the lessons learnt from Three Mile Island, Chernobyl and September 11, 2001 events. In the event of proposals to export nuclear reactors which do not meet these safety objectives, ASN will not hesitate to declare that such reactors could not be built in France.

Quarterly assessment of radiotherapy events

Twenty events, classified as level 1 on the ASN-SFRO scale, were reported between 1 January and 31 March 2010. Although these events are not expected to have any impact on patients' health, they are analysed to see if any lessons can be learnt from them (particularly in terms of organisation) and to avoid any recurrence.

Raw materials containing naturally occurring radionuclides

Some industrial processes concentrate natural radionuclides contained in raw materials, manufactured products or production waste. ASN worked in collaboration with IRSN, the French National Institute for Radiation Protection and Nuclear Safety, to assess the exposure of workers and the population at large to this “technologically enhanced natural radioactivity” [1].

Medical imaging: international harmonisation of practices

At a colloquium organised by the World Health Organisation (WHO), 1-3 March 2010, in which the French Nuclear Safety Authority (ASN) participated, representatives of 23 international organisations and learned societies agreed on a "roadmap" aimed at both establishing international good practice guidelines for medical imaging issues and at facilitating their implementation. The "roadmap" also envisages monitoring and evaluation of the impact of this approach for the various clinical situations.
