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.
The article does not directly address emergency response, however it did address medical stories as being helpful to the public to feel supported and reach out when they realized they had a psychological condition. This is important in society, because if someone can get treated for something, or at least know they have it an take precautions, then they help themselves feel more comfortable and be more successful, they reduce the strain on those around them, and they make it easier for healthcare providers, if there is ever a related issue.
