Nuclear power plant: state of knowledge of the population living in the area of the Cattenom special intervention plan. A cross sectional study.

In France information campaigns are periodically conducted within a 10 km radius of nuclear power plants on the protective actions to be adopted in the event of a nuclear accident. The aim of this study was to assess the knowledge of the inhabitants of the Cattenom PPI area on the recommended actions to be adopted in the event of a nuclear accident after the information campaign that took place from 2016 to 2017 and compare its results with a similar study carried out before the information campaign. We performed a cross-sectional study in the Cattenom PPI area after the 2016-2017 information campaign. We administered questionnaires in ten municipalities selected by lot. These questionnaires contained queries on the general protective actions and required approach to taking potassium iodide (KI). The results obtained were compared with the results of a study conducted before the information campaign in the same area. Out of 200 questionnaires administered, 122 people responded. Only 40% of respondents remembered the information campaign. Only 16% knew all of the recommended protective actions. 78% of households had KI and only 60% knew the objective of KI intake. Compared to the results of the study before the information campaign, KI coverage was better (69% versus 78%, p = 0.02) and the dosage was better known (16% versus 28%, p = 0.0003). This study provides an overview of the effectiveness of information campaigns on the procedure in the event of a nuclear accident. This study highlights the insufficient knowledge of people living in the Cattenom PPI area.
