Određivanje izloženosti korisnika mobilnih telefona zračenju elektromagnetnog polja
Sažetak
Uvod/Cilj. Tokom zadnjih godina rasprostranjeno korišćenje mobilnih telefona ima za posledicu povećano izlaganje ljudi zračenju elektromagnetnog polja, a time i rizicima za svoje zdravlje. Povećano korišćenje mobilnih telefona na malom rastojanju nameće pitanja i izaziva sumnju u bezbednost njihovih korisnika. Cilj ove studije bio je da utvrdi izloženost korisnika mobilnih telefona zračenju elektromagnetnog polja merenjem jačine elektromagnetnog polja u različitim okruženjima na rastojanju od 1 do 30 cm od korisnika telefona. Metode. U ovoj studiji vršena su merenja izloženosti korisnika raznih marki mobilnih telefona zračenja elektromagnetnog polja mobilnih telefona pomoću faktora koji se odnose na poziv: gradska/seoska zona, zatvoren/otvoren prostor i kretanje/mirovanje tokom poziva. Razni tipovi mobilnih telefona postavljani su okrenuti prema sondi za merenje na rastojanja od 1 cm, 10 cm, 20 cm i 30 cm. Rezultati. Najjače elektromagnetno polje zabeleženo je kod poziva u seoskoj zoni (zatvoren prostor), dok je najslabije zabeleženo za one u gradskoj zoni (otvoren prostor). Pozivi sa telefona iz kola koja se kreću pokazali su slične rezultate kao pozivi iz zatvorenog prostora; međutim, pozivi sa telefona iz kola koja se kreću izlažu korisnika duplo jačem električnom polju nego pozivi iz mirovanja (bez kretanja). Zaključak. Zračenje elektromagnetnog polja zavisi od snage mobilnog telefona i faktora kao što su gradska ili seoska sredina, otvoren ili zatvoren prostor, kretanje ili mirovanje, i rastojanje mobilnog telefona od korisnika telefona. Preporučljivo je držati mobilni telefon na bezbednom rastojanju – 10, 20 ili 30 cm od tela (naročito glave) tokom razgovora.
