Abstract

Radiofrekvencijsko elektromagnetsko polje u ljudskom okolišu je uglavnom uzrokovano sistemom mobilne komunikacije. Mobilni uređaji su najnaprednija i brzorastuća tehnologija širom svijeta što pokazuje činjenica da se u posljednjih 10 godina njihova uporaba povećala čak 3 puta. Stvorila se opravdana zabrinutost zbog mogućih štetnih učinaka koja je posebno orijentirana na razvoj tumora mozga. Poznato je da tumori mogu nastati prilikom izlaganja ionizirajućem zračenju jer se mijenja struktura ozračene tvari. No neionizirajuće zračenje koje nema tako veliku energiju da može iz ljuske atoma izbaciti elektron i na taj način ionizirati tvar, ne može izravno oštetiti stanicu biološkog organizma na kemijskom nivou. Iako je provedeno mnogo istraživanja utjecaja mobilnog zračenja na ljudski organizam, tumorske stanice i na sam razvoj tumora, ono još uvijek nije u potpunosti razjašnjeno. Mnogo dobivenih rezultata je različito te se i dalje ne zna točan utjecaj mobilnih telefona. Međunarodna agencija za istraživanje raka je 2011. godine klasificirala radiofrekvencijsko zračenje u skupinu potencijalnih karcinogena za ljude. Sve do danas, većina objavljenih studija provedenih na korištenju mobilnih telefona i tumora mozga nisu pokazale povećani rizik što se tiče cjelokupnog korištenja. Ipak, dobiveni su i pozitivni rezultati u nekoliko manjih analiziranih podskupina, kao što je slučaj s dugoročnim korisnicima i analognim telefonima gdje je u oba slučaja blago povišen rizik od razvoja tumora. Osim toga, zračenje posljedično djeluje na ljudsko zdravlje uništavajući DNA molekulu i mijenjajući ekspresije gena i proteina u organizmu. Da bi se potvrdile dosadašnje teze i pobliže razjasnio utjecaj mobilnog zračenja na biološki organizam potrebno ih je potkrijepiti dodatnim podacima iz budućih istraživanja.

Abstract (english)

Radiofrequency electromagnetic field in the human environment is mainly caused by mobile communication systems. Mobile phones are the most rapidly growing telecommunication technology worldwide which is shown by the fact that in the last ten years their use has increased three times. It created justified concerns about potential adverse effects which are focused on development of brain tumors. It is known that tumors can occur when exposed to ionizing radiation because it changes the structure of the irradiated substance. But non-ionizing radiation which has not such a large energy to eject the electron out of atoms shells and thus ionize the substance, can’t directly damage the cells of a biological organism in a chemical level. Although there were a lot of research about influence of the radiation on the human body, tumor cells and tumor development itself, it is still not fully understood. Many of the results is different and it is still not known the exact impact of mobile phones. The International Agency for Research on Cancer in 2011 classified the radiofrequency radiation to a group of potential carcinogenic to humans. Until now, the majority of published studies conducted on the use of mobile phones and brain tumors have not shown an increased risk as regards the overall use. Nevertheless, the obtained results were positive in several subgroups, as is the case with the long-term users and analog phones where in both cases the risk of developing tumors is slightly elevated. In addition, radiation consequently effect on human health by destroying the DNA molecule and altering the expression of genes and proteins in the body. In order to confirm previous theses and closely clarify the impact of mobile radiation on biological organisms, they need to be supported by additional data from future studies.
