Fig . 1 . Word cloud of the top 100 nouns and adjectives in all the guidelines combined .
All guidelines follow relatively the same structure ( Fig . 2 ), meaning that all subthemes are represented , on average , in the same frequency with ‘ Health ’ and ‘ Stakeholder involvement ’, the most represented subthemes at 28 % and 22 %, respectively .
3.2 . Correspondence analysis and co-occurrence network
Figures 3a and 3b display the correspondence analysis of the themes presented in a two-dimensional diagram . From the distribution of themes , dimension 1 ( 53,4 % of data ), predominantly represents the ‘ Food ’, ‘ RPPs ’, ‘ Psychological impact ’, ‘ Stakeholder involvement ’, ‘ Ecosystems ’, ‘ Land ’ and ‘ Waste ’ subthemes . Dimension 2 ( 18,8 % of data ) represents the ‘ Food ’, ‘ RPPs ’, ‘ Psychological impact ’, ‘ Stakeholder involvement ’, ‘ Ecosystems ’, ‘ Land ’, ‘ Waste ’ and ‘ Economy ’ sub-themes . Dimension 3 ( 10,8 % of data ) mainly represents the ‘ RPPs ’, ‘ Health ’, ‘ Waste ’, ‘ Ecosystems ’ and ‘ Stakeholder involvement ’ subthemes .
Correspondence analysis from the three-dimension and cooccurrence networks ( Figs . 3a , 3b and 4a ) give similar results and indicate diversity in the themes focused on each guideline . It is important to note that a guideline located far from a theme does not imply a complete absence of discussion about that theme , but rather more of a situation instead of a yes / no . Thus , the following can be inferred : – The ‘ Health ’ theme , located in the center seems to be a common theme among guidelines ;
– The ‘ Stakeholder involvement ’ theme is a common theme in all guidelines , but less in ‘ USA EPA ’, ‘ Codirpa ’ and ‘ STUK ’ guidelines ;
– The ‘ Radiological protection principles ’ theme is focused by the ‘ UK HM ’, ‘ IAEA GSG11 ’, ‘ IAEA GSG15 ’, ‘ NCRP175 ’, ‘ IFRC ’, ‘ ICRP ’, ‘ PHE ’ and ‘ NEA ’ guidelines ;
– The ‘ Land ’ and ‘ Waste ’ themes are mentioned more by the ‘ USA EPA ’, ‘ IAEA GSG15 ’, ‘ Codirpa ’ and ‘ STUK ’ guidelines ;
– The ‘ Food ’ theme is focused mostly by ‘ STUK ’ and ‘ Codirpa ’ guidelines ;
– The ‘ Ecosystem ’ theme is mentioned more by ‘ IAEA GSG 15 ’, ‘ STUK ’ and ‘ Codirpa ’ guidelines ;
– The ‘ Economy ’ theme seems to be mentioned more by ‘ PHE ’, ‘ Canada ’, ‘ ICRP ’ and ‘ Codirpa ’ guidelines ;
– The ‘ Psychological impact ’ theme seem to be mentioned more by ‘ IAEA GSG11 ’, ‘ IFRC ’, ‘ Canada ’, ‘ PHE ’ and ‘ NEA ’ guidelines .
