Tekstim - zaščita pred elektromagnetnim sevanjem

Abstract

Elektromagnetna sevanja (EMS) so prisotna povsod v našem okolju in so nevidna za človeško oko. Poleg naravnih izvorov sevanj so v elektromagnetnem spektru prisotna tudi sevanja, katerih izvor je povzročil človek. Elektromagnetni spekter sestavljajo ionizirajoča sevanja, kamor spadajo gama žarki in X-žarki, ter neionizirajoča sevanja, ki nimajo dovolj energije, da bi razbila molekularne vezi. Industrializacija predstavlja glavnino umetnih izvorov elektromagnetnih sevanj (EMS) - elektrika, mikrovalovi in radiofrekvenčna sevanja - se nahajajo v relativno dolgih valovnih dolžinah in nizkih frekvencah elektromagnetnega spektra. Ti izvori nimajo dovolj energije, da bi razbijali kemične vezi. Učinki elektromagnetnih sevanj na človeško telo niso odvisni samo od stopnje sevanja ampak tudi od frekvence in energije. Če so sevanja dovolj močna, lahko inducirajo tok znotraj človeškega telesa in povzročijo vrsto efektov, kot so segrevanje in elektro šok, odvisno od amplitude in vrste frekvence. TEKSTINA d.d iz Ajdovščine je razvila novo blagovno znamko Tekstim, ki učinkovito ščiti pred EMS. Tekstim tkanine in preje bombažnega tipa imajo vgrajena nerjaveča kovinska vlakna, ki uspešno ščitijo pred škodljivimi EMS. Preje in tkanine Tekstim so namenjene izdelovanju lahkih zaščitnih oblačil, dnevnih oblek, spodnjega perila, dekorativnih tkanin in drugih zaščitnih izdelkov. Tekstim je bil testiran na Inštitutu za varovanje zdravja Republike Slovenije. Rezultati testov dokazujejo, da Tekstim zadrži nad 80 % vpadnega signala EMS v frekvenčnem območju 10-1000 MHz.

Secondary abstract:	Electromagnetic fields (EMF) are present everywhere in our environment but are invisible to the human eye. Besides natural sources, the electromagnetic spectrum also includes fields generated by human-made sources. In the electromagnetic spectrum, gamma rays given off by radioactive materials, cosmic rays and X-rays carry this property and are called »ionizing radiation«. Fields the quanta of which are insufficient to break molecular bonds are called »non-ionizing radiation«. Man-made sources of electromagnetic fields that form a major part of industrialized life electricity, microwaves and radiofrequency fields are found at the relatively long wavelength and low frequency end of the electromagnetic spectrum and their quanta are unable to break chemical bonds. The effects of electromagnetic fields on a human body depend not only on their field level but on their frequency and energy as well. These fields induce currents within a human body, which, if sufficient, can produce a range of effects such as heating and electrical shock, depending on their amplitude and frequency range. The textile company TEKSTINA d. d. from Ajdovščina has developed efficient protection against EMF called TEKSTIM. Tekstim stands for cotton based fabrics and yarns to which rustproof metallic fibers have been added, thus offering an active shielding against harmful radiation of EMF. The yarn and fabric are designed for manufacturing of light protective working and casual clothes, underwear, furnishing fabric and other protective pieces of clothing. Tekstim has been tested by The Institute of Public Health of the Republic of Slovenia. The results have shown that Tekstim efficiently neutralizes over 80 % of the EMF incidence field in the frequency range 10 - 1000 MHz.
