content of nuclear disaster prevention-related websites. Our search was able to cover all relevant Japanese-language websites related to nuclear disaster prevention because web page materials were collected until saturation was reached. However, the present study also has some limitations. First, since the evaluation covered only Japanese-language websites related to nuclear disaster prevention, it is difficult to generalize the results to websites related to nuclear disaster prevention in other languages, printed materials, smartphone applications, videos, and so on. Second, because this study included only freely accessible websites, it is also difficult to generalize the results to paid websites that may contain more detailed information about nuclear disaster prevention. However, it is likely that the first place a person newly interested in radiation would look for information would be a freely accessible website rather than a paid one. Third, because some of the evaluation indicators on the website, such as the JAMA Benchmark Criteria( Silberg et al., 1997) and the GQS( Bernard et al., 2007), have not been fully examined in terms of reliability and validity, caution is needed in interpreting whether they adequately assess the content that one wishes to evaluate. Fourth, if the amount of text in nuclear disaster preparedness materials is large, the understandability, actionability, and credibility of the materials are likely to be evaluated as high. However, materials with a large amount of information may not be easily accessed from any location, and people may be less inclined to read these materials for predisaster preparedness. It has been reported that the percentage of people who save and understand emergency preparedness pamphlets is low( Hellier et al., 2014). In the future, the usefulness of these materials as pamphlets may also need to be evaluated.
In this study, we evaluated the overall quality of existing nuclear accident prevention brochures and were able to identify the characteristics of the materials by source. However, we have not yet been able to create and provide materials adapted to the“ average adult” and suggest appropriate search methods. Studies have been conducted
