Two handbooks have been developed in conjunction with a wide range of stakeholders that provide assistance in the management of contaminated food production systems and inhabited areas following a radiological incident. Emergency centres in Member States not involved in the development of these handbooks were invited to take part in demonstration activities to establish whether the handbooks would be useful for the purposes of contingency planning and accident management. Some eight centres took part. Emergency exercises or similar events based on scenarios involving contamination of the foodchain and inhabited areas were used. Feedback from all of the demonstrations was positive with constructive criticism given on how to improve the navigation, structure and format of the handbooks. All of the key improvements highlighted during the demonstrations were taken into account and included in version 2 of the handbooks. Two additional demonstrations took place in Denmark and Slovakia to investigate the appropriateness and applicability of a stakeholder participatory process when applying the handbooks. These stakeholders expressed their willingness to discuss the issues at stake from contamination of food production systems and inhabited areas and gave a clear commitment to continue the process.
