Assessing radiation risk perception by means of a European stakeholder survey.

It is increasingly recognised that stakeholder views can be essential for ascertaining the credibility of those entrusted with protection of the public and workers against radiation risks, the robustness of the approaches to protection and the relevance of research underpinning radiation protection (RP). The CONCERT European Joint Programme of RP research included consideration of stakeholder views. These were evaluated by means of a publicly available survey, translated into 15 languages, to encourage responses from a wide range of European countries. The survey ran in 2017 and received some 1961 responses from many countries, although response rates varied widely between countries. The survey respondents were largely highly educated, with many having a professional connection to RP or the use of radiation in medicine or industry. Survey results indicated a high level of scientific/technical knowledge relevant to RP and indicated a general trust of most actors involved in the RP field, perhaps unsurprisingly given the nature of the sampled population. Most expressed a reasonable level of satisfaction with the information available to them on radiation risk, but there is clearly room for improvement. Additionally, the survey identified potential training needs amongst the groups who responded. It is concluded that, while the survey results are limited by the non-representativeness of the respondents by comparison with the population of the European Union as a whole, it has been successful in gaining insights into areas where communication could be improved, where professional training gaps are present and where research could help to build wider trust in RP.

Better use of European (regional) resources.

In case of an accidental release of radioactivity and subsequent contamination of the food chain, many samples need to be collected and analysed, and this is far from being a simple issue. The determination of contamination levels requires accredited laboratories, approved and certified procedures and methods, transparency and above all prompt results, as stakeholders in general cannot afford waiting. Adequate decisions require fixed norms, stable in time, and accepted internationally. Moreover, an effective policy relies on traceability of products as well. There are huge requirements of harmonisation of procedures, traceability of data, database management, priority settings etc. Accredited laboratories tend to make use of reliable techniques but these have been optimised for low radiation levels and high accuracy for routine analyses, often in the framework of radiological surveillance of the territory, drinking waters or the food chain. It is obvious that such procedures, although very accurate and sensitive, are not suited for urgent decisions in crisis situations. Similarly, accredited analysis methodologies may start from large quantities of product in order to decrease limits of detection; however, this involves sometimes long times for drying or chemical treatment, introducing important delays. Furthermore, large quantities of samples would simply result in the saturation of the analytical capabilities of one country. Adequate actions and informed decisions during a nuclear accident will require an analytical infrastructure that individual countries do not have; hence there is a clear need to establish regional collaboration and co-operation. This paper includes an example of such collaborative work and mutual assistance, and also touches on how sharing tools for decision making, analytical resources, sample collection procedures and analysis would promote trust, reliablity in the results, a common approach toward minimizing the effects of a radiological disaster and above all unity. Last but not least, this paper also poses a challenge: Nuclear accident management implies that all responsible parties have to guarantee that decision support systems have access to data and information in the best available and consistent manner. This will not be achieved in an independent and isolated manner.
