Data comes in post form, with the titles and a small blurb and you can click for the whole article. There are tags for each post and they are sorted into folders/categories as mentioned previously.
The article used many letters written between people, which was an interesting thing see, as that was a good source of information for the fires back many years ago. In using a variety of disasters over many years to write the article, the author had to use different types of sources as society and technology developed.
The claims were supported by the laws and cases that have been caried out. The three parts of the law were explained and examples of situations were given.
I looked up how emergency responders deal with mental health, since the method that was described in this article is no longer recommended. I also investigated the types of disaster that people around the world face each year, besides for weather disasters. Furthermore, I looked at a map of the types of disasters across the globe.
The pdf did not include the bibliography, however I would assume that a lot of the scientific information came from other, more medical/chemical rather than sociological, Chernobyl research.
