To prepare a coherent system of recommendations designed for the control of environmental risks caused by naturally occurring radioactive materials (NORMs), it is necessary to realise causes of concern and define in clear terms the risk scenarios.
Based on earlier paper in this journal, as well as on new data concerning factors predetermining individual susceptibility to silicosis, we propose a comprehensive system of recommendations aimed at increasing the working population's resistance against the harmful action of silica dust.
Using the GRADE system (Grading of Recommendations, Assessment, Development and Evaluation) [7, 8], the literature was analyzed and recommendations were formulated.
The GRADE system (Grading of Recommendations Assessment, Development and Evaluation) and a literature analysis were used to formulate the recommendations [13, 14].
The methodology used was inspired by the GRADE system (Grading of Recommendations Assessment, Development and Evaluation) for rating clinical guidelines (http://www.gradeworkinggroup.org/links.htm), the originality of which stems primarily from three assertions.

System of the recommendation ITU-R BT.709 [1] can only provide part of the visible colors that the human eyes can see.
Consequently, no evidence-based recommendations, neither any system of ranking of recommendations, is possible.
An increasing number of organizations have come to an agreement to use a common system for formulation of recommendations in guidelines.
However, this system, the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach, has scarcely been used within WHO [ 9, 10].
