1 ERICA an overview Brenda Howard, NERC 1

2 ERICA: Environmental Risk from Ionising Contaminants: Assessment and Management Overall objective to provide an integrated approach to scientific, managerial and societal issues concerned with the environmental effects of contaminants emitting ionising radiation, with emphasis on biota and ecosystems. The final outcome of the project will be the ERICA integrated approach to assessment and management of environmental risks from ionising radiation, using practical tools. 2

3 Division of tasks WP5 Management: Deliver the ERICA Integrated Approach Co-ordinate Integrate WP1 Assessment Tools Test Refine Bridge Gap WP3 Communication and Decision-making Stakeholder Dialogue WP4 Case Studies Apply Validate WP2 Risk Characterisation 3

4 WP1: the assessment tool Five Tasks 1. Modification and re-population of FREDERICA 2. Transfer assessment 3. Development of complex geometry dose models 4. Dosimetry - reconstruction and experimental support 5. Development of environmental assessment tool 4

5 WP1: the prototype software 5

6 WP2: risk characterisation Three Tasks 1. Risk characterisation methodologies Review carried out 2. Extrapolation issues, with experimentation Protocols developed Experiments started 3. Development of good practice guidance 6

7 The proposed tiered approach Problem Formulation Tier 1 = Screening EXIT Tier 3 = Site Specific/Full Assessment Tier 2 = Generic Assessment Management Action Required 7

8 WP3: decision-making guidance and Communication Objectives Liaison with stakeholders EUG established = 53 organisations Seven Events in three years for receiving inputs Delivery of D8: decision-making guidance Proposed table of content Based on themes for the EUG events To tie in with interim tiered approach, i.e. D4a 8

15 Protection of the Environment from Ionising Radiation in a Regulatory Context PROTECT 15

16 Objective The primary objectives of this proposed co-ordinated action are to evaluate the practicability and relative merits of different approaches to protection of the environment from ionising radiation and to compare these with methods used for non-radioactive contaminants. This will provide a basis on which the EC could develop protection policies and revise its Basic Safety Standards, and ensure a fruitful collaboration with, and constructive input into, current ICRP and IAEA task groups. 16
