The aim of the study was to measure and evaluate the attenuation of the electromagnetic field using personal protective textile accessories within three frequencies: 825 MHz, 1760 MHz and 2109 MHz. Measurements on the human head phantom were performed 1. without a protective accessory, 2. with the protective cap containing the silver fibres, 3. with the visor cap containing the silver fibres, 4. with an ordinary aluminium foil, 5. with the classic cap and 6. with the visor cap without any protective elements. The best shielding effectiveness was provided by the protective cap containing a silver, which covered almost the entire area of the head. It provided the highest attenuation for all frequencies, considering the average from each side (left, right, top of the head): 10.85 ± 1.44 dB (825 MHz), 14.55 ± 4.30 dB (1760 MHz) and 12.45 ± 4.88 dB (2109 MHz). The highest value for particular side of the head was observed for the visor cap containing a silver 19.25 ± 6.95 dB for the top of the head (1760 MHz). For the classic caps, the attenuation was lower than 1dB.

Celem pracy był pomiar i ocena tłumienia pola elektromagnetycznego za pomocą tekstylnych akcesoriów ochrony osobistej w zakresie trzech częstotliwości: 825 MHz, 1760 MHz i 2109 MHz. Pomiary na fantomie głowy ludzkiej wykonano 1. bez akcesorium ochronnego, 2. z nakładką ochronną zawierającą włókna srebrne, 3. z nakładką przyłbicy zawierającą włókna srebrne, 4. ze zwykłą folią aluminiową, 5. z klasyczną i 6. z nakładką z daszkiem bez żadnych elementów ochronnych. Najlepszą skuteczność ekranowania zapewniała nasadka ochronna zawierająca srebro, która pokrywała niemal całą powierzchnię głowy. Zapewniał najwyższe tłumienie dla wszystkich częstotliwości, biorąc pod uwagę średnią z każdej strony (lewa, prawa, czubek głowy): 10,85 ± 1,44 dB (825 MHz), 14,55 ± 4,30 dB (1760 MHz) i 12,45 ± 4,88 dB (2109 MHz). Najwyższą wartość dla poszczególnych stron głowy zaobserwowano dla nasadki przyłbicy zawierającej srebro 19,25 ± 6,95 dB dla czubka głowy (1760 MHz). Dla klasycznych czapek tłumienie było mniejsze niż 1dB.
