SCHEDULE 3 Consequences Assessment

1.  The following requirements shall be complied with in the assessment of consequences required by regulation 5.

2.  The assessment shall be based on a suitable and sufficient range of source terms representing a range of potential radiation emergencies which might arise from the work with ionising radiation.

3.  The calculations undertaken in support of the assessment shall consider a range of weather conditions (if weather conditions are capable of affecting the extent of the impact of the radiation emergency) to account for—

(a) the likely consequences arising from such conditions; and

(b) consequences which are less likely, but with greater impact.

4.  The assessment shall consider the consequences of the potential radiation emergencies identified in regulation 4 on the population within the geographical extent of the potential radiation emergency, accounting for different characteristics, including, for example age and other characteristics which would render specific members of the public especially vulnerable.

5.  The assessment shall consider what would be an effective and, where relevant, equivalent dose to the thyroid in the context of each potential radiation emergency identified.

6.  The assessment shall include all relevant pathways by which members of the public could be exposed to radiation in the context of each potential radiation emergency identified.

7.  The assessment shall identify any protective action that may need to be taken for the range of potential radiation emergencies.

8.  The assessment shall assess the consequences of suitable and sufficient source terms by distance and by exposure pathway, and the distances to which protective action would be required based on the United Kingdom’s Emergency Reference Levels, published by Public Health England(1).

9.  In this Schedule “source term” means the radioactivity which could give rise to direct external exposures from the premises or which could be released to the environment in a radiation emergency and, for releases, includes—

(a) the amount of each radionuclide released;

(b) the time distribution of the release;

(c) the energy associated with atmospheric release; and

(d) the likely chemical and physical form of the radionuclides in the release.

Regulation 7(3)

SCHEDULE 4 Particulars to be included in a consequences report

PART 1 Factual Information

1.  The following factual information shall be provided in the operator’s consequences report—

(a) the name and address of the operator;

(b) the postal address of the premises where the radioactive substance will be processed, manufactured, used or stored, or where the facilities for processing, manufacture, use or storage exist;

(c) the date on which it is anticipated that the work with ionising radiation will commence or, if it has already commenced, a statement to that effect.

PART 2 Recommendations

2.  The operator shall include the following recommendations in the consequences report—

(a) the proposed minimum geographical extent from the premises to be covered by the off-site emergency plan arranged by the Executive; and

(b) the minimum distances to which urgent protective action may need to be taken, marking against each distance the timescale for implementation of the relevant action.

3.  In relation to a minimum geographical extent recommended under paragraph 2, the operator shall also include within the consequences report—

(a) the recommended urgent protective actions to be taken within that zone, if any, together with timescales for the implementation of those actions; and

(b) details of the environmental pathways at risk in order to support the determination of food and water restrictions in the event of a radiation emergency.

PART 3 Rationale

4.  The operator shall set out the rationale supporting each recommendation made in the consequences report.

5.  In particular, the operator shall set out—

(a) the rationale for its recommendation on the minimum distances for which urgent protective action may need to be taken; and

(b) where the operator and the Executive have agreed that no off-site planning is required, and therefore no emergency planning is recommended, the rationale for that agreement.

Regulations 10(3) and 11(3)

SCHEDULE 5 Information to be included in emergency plans

PART 1 Information to be included in an operator’s emergency plan

1.  The information referred to in regulation 10(3) is as follows—

(b) the arrangements to co-ordinate the on-site mitigatory action;

(c) the name or position of the person with responsibility for liaison with the Executive;

(d) for conditions or events which could be significant in bringing about a radiation emergency, a description of the action which should be taken to control the conditions or events and to limit their consequences, including a description of the safety equipment and resources available;

(e) the arrangements for limiting the risks to persons on the premises including how warnings are to be given and the protective action persons are expected to take on receipt of a warning;

(f) the arrangements for providing early warning of the incident to the emergency services, identified in the off-site emergency plan to set the off-site emergency planning in motion, the type of information which should be contained in an initial warning and the arrangements for the provision of more detailed information as it becomes available;

(g) the arrangements for providing assistance to the Executivewith its off-site protective action;

(h) the arrangements for providing information about the incident to the Executive;

(i) the arrangements for dealing with emergency exposures including the dose levels which have been determined as appropriate for the purposes of putting into effect the emergency plan;

(j) the arrangements to prioritise keeping doses within the reference levels set out in regulation 19(1);

(k) any specific arrangements which take account of lessons learned from past emergency situations, whether at the operator’s premises or otherwise;

(l) what protective action is proposed to be taken, and how far each such action extends within any detailed emergency planning zone; and

(m) the arrangements which the operator considers may assist in the transition from a radiation emergency to an existing exposure situation, including who will be involved in such transition, what information they are to receive and when.

PART 2 Information to be included in the off-site emergency plan

Regulations 10(3) and 11(3)

SCHEDULE 6 Principles and purposes of emergency plans

PART 1 Principles to which emergency plans shall have regard

1.  Any person with responsibility for preparing an emergency plan under these Regulations shall consider the following principles when preparing that plan—

(a) the necessity for the plan to respond to the particular characteristics of a given radiation emergency as those characteristics emerge;

(b) the necessity to optimise protection strategies to ensure that the proposed response, as a whole, is predicted to do more to mitigate the radiation emergency and facilitate transition from that emergency to an existing exposure situation than to increase its duration or consequences, taking into account—

(i) the health risks arising from exposure to ionising radiation as a result of the radiation emergency, in both the long and the short term;

(ii) the economic consequences of the radiation emergency;

(iii) the effects of the disruption, both on the premises and the area immediately surrounding it, and on the public perception of the effects of the radiation emergency;

(c) the necessity of avoiding, so far as possible, the occurrence of serious physical injury to any person; and

(d) the necessity of ensuring that an appropriate balance is struck between the expected harms and benefits of any particular protective action so as to maximise the benefit of that action.

PART 2 Purposes of emergency plans

2.  Any person with responsibility for preparing an emergency plan under these Regulations shall ensure that the plan, if implemented, would fulfil the following purposes—

(a) to reduce or stop the effects of the radiation emergency;

(b) to reduce the exposure to individuals and to the environment resulting from the release of ionising radiation;

(c) if necessary, to ensure that provision is made for the medical treatment of those affected by the radiation emergency; and

(d) to prioritise the implementation of the plan in relation to any person exposed to a dose in excess of the reference levels set out in regulation 19.

Regulation 20(3)

SCHEDULE 7 Prior information for members of the public

2.  The various types of radiation emergency identified and their consequences for the general public and the environment.

3.  Protective action envisaged to alert, protect and assist the general public in the event of a radiation emergency.

4.  Appropriate information on protective action to be taken by the general public in the event of a radiation emergency.

5.  The authority or authorities responsible for implementing the protective action referred to in paragraphs 3 and 4 above.

6.  The extent of the detailed emergency planning zone.

PART 2 Information in relation to outline planning zones

7.  Where the information set out at paragraphs 1 to 5 can be obtained.

8.  The extent of the outline planning zone.

9.  The factors which would cause the plan in respect of the outline planning zone to be triggered, and whether there are any areas of detailed planning within the outline planning zone as defined at paragraph 4 of Part 2 of Schedule 5.

Regulation 21(4)

SCHEDULE 8 Information to be supplied in the event of a radiation emergency

1.  Information on the type of emergency which has occurred, and, where possible, its characteristics, for example, its origin, extent and probable development.

2.  Advice on protective action which may include, depending on the type of emergency—

(a) any restrictions on the consumption of certain foodstuffs and water supply likely to be contaminated;

(b) any basic rules on hygiene and decontamination;

(c) any recommendation to stay indoors;

(d) the distribution and use of protective substances;

(e) any evacuation arrangements;

(f) special warnings for certain population groups.

3.  Details concerning any announcements recommending cooperation with instructions or requests by the Executive.

4.  Where an incident which is likely to give rise to a release of radioactivity or ionising radiation has taken place but no release has yet occurred, the information and advice should include the following—

(a) details of the relevant communications channels on which information about the incident will be available;

(b) preparatory advice to establishments with particular collective responsibilities; and

(c) recommendations to occupational groups particularly affected.

5.  If time permits, information setting out the basic facts about radioactivity and its effects on persons and on the environment.

6.  In paragraph 4(b), “establishments with particular collective responsibilities” means hospitals, care homes, schools or similar establishments.
