The reference individual exposure levels for the participants, expressed in terms of effective dose, should be set as follows:

a) The effective dose which may be received by personnel in group 1 is 100 mSv.It is set at 300 millisieverts when the intervention measure is aimed at protecting other people.

Information of the population in a radiological emergency

The procedures for informing the population of a radiological emergency are detailed in a specific directive (directive 89/618/Euratom of 27 November 1989 on informing the general public about health protection measures to be applied and steps to be taken in the event of a radiological emergency). This directive was transposed into French law by:
– decree 2001-470 of 28 May 2001 concerning information of the population and amending decree 88-622 of 6 May 1988 concerning emergency plans and two implementing orders (order of 30 November 2001 concerning the creation of an emergency alert system around a basic nuclear installation with an off-site emergency plan and the order of 21 February 2002 concerning information of the population);
– decree 2005-1179 of 13 September 2005 concerning radiological emergency situations.
