1. These arrangements shall apply to the notification and provision of information whenever a Member State decides to take measures of a wide-spread nature in order to protect the general public in case of a radiological emergency following:
(a) an accident in its territory involving facilities or activities referred to in paragraph 2 from which a significant release of radioactive material occurs or is likely to occur; or
(b) the detection, within or outside its own territory, of abnormal levels of radioactivity which are likely to be detrimental to public health in that Member State; or
(c) accidents other than those specified in {a) involving facilities or activities referred to in paragraph 2 from which a significant release of radioactive material occurs or is likely to occur; or
(d) other accidents from which a significant release of radioactive materials occurs or is likely to occur.
2. The facilities or activities referred to in paragraph 1 (a) and 1 (c) are the following:
(a) any nuclear reactor, wherever located;
(b) any other nuclear fuel cycle facility;
(c) any radioactive waste management facility;
(d) the transport and storage of nuclear fuels or radioactive wastes;
(e) the manufacture, use, storage, disposal and transport of radioisotopes for agricultural, industrial, medical and related scientific and research purposes; and
(f) the use of radioisotopes for power generation in space objects.
Article 2 

1. When a Member State decides to take measures as referred to in Article 1, that Member State shall:
(a) forthwith notify the Commission and those Member States which are, or are likely to be, affected of such measures and the reasons for taking them;
(b) promptly provide the Commission and those Member States which are, or are likely to be, affected with available information relevant to minimizing the foreseen radiological consequences, if any, in those States.

Article 3 

1. The information to be provided pursuant to Article 2 (1) (b) shall, without jeopardy to matters of national security, include, as far as practicable and appropriate, the following:
(a) the nature and time of the event, its exact location and the facility or the activity involved;
(b) the assumed or established cause and the foreseeable development of the accident relevant to the release of the radioactive materials;
(c) the general characteristics of the radioactive release, including the nature, probable physical and chemical form and the quantity, composition and effective height of the radioactive release;
(d) information on current and forecast meteorological and hydrological conditions, necessary for forecasting the dispersion of the radioactive release;

(f) the results of measurements of foodstuffs, feeding-stuffs and drinking water;
(g) the protective measures taken or planned;
(h) the measures taken, or planned, to inform the public;

Any Member State, upon receipt of the information set out in Articles 2 and 3, shall:

((a)) promptly inform the Commission of the measures taken and recommendations issued following the receipt of such information;
((b)) inform the Commission, at appropriate intervals, of the levels of radioactivity measured by their monitoring facilities in foodstuffs, feedingstuffs, drinking water and the environment.

1. Upon receipt of the information referred to in Articles 2, 3 and 4, the Commission shall, subject to Article 6, immediately forward it to the competent authorities of all other Member States. Likewise the Commission shall forward to all Member States any information it receives about significant increases in the level of radioactivity or about nuclear accidents in non-Community countries and especially those adjacent to the Community.
2. Detailed procedures for the transmission of the information referred to in Articles 1 to 4 shall be agreed by the Commission and the competent authorities of the Member States and tested at regular intervals.
3. Each Member State shall indicate to the Commission the competent national authorities and points of contact designated to forward or receive the information set out in Articles 2 to 5.
