Purpose: The aim of this article is to pay attention on the necessary of protection of the people and devices from the harmful electromagnetic radiation. The special role play the screens (materials or systems) for shielding which have a very diversified construction depending on the frequency of electromagnetic fields. Design/methodology/approach: In the paper a problem of electromagnetic fields shielding was presented. Moreover, the occupational risk assessment at the vacuum sublimation position was showed. Findings: The screening methods and materials used for screens were discussed. The threats occurring at the vacuum sublimation position and the preventive actions decreasing the risk level were presented. Research limitations/implications: The paper presents the one of the methods for screens fabrication – vacuum sublimation in a simple laboratory vacuum sublimation equipment. The structure testing and investigation of thickness of fabricated screen (constructed from four layers: aluminum – polypropylene – aluminum – metallic glass of Metglas type) were carried out. The occupational risk assessment was made by three-stage scale method according to PN-N-18002 standard. Practical implications: The results of microscopic observation of fabricated material system unequivocally reject the vacuum sublimation method using a laboratory vacuum sublimation equipment for the screens fabrication. Originality/value: In the article the different kinds of threats occurring at the vacuum sublimation position were presented. The various preventive actions were proposed.
