SMARTPHONE E TUMORI AL CERVELLO ? di Maira Alcantara

Possiamo confermare che l’umo del terzo millennio sia divenuto con il passare degli anni cellular-dipendente, un po’ per la facilità di poter avere internet in tasca in ogni momento, un po’ per la comunicazione tramite i social network e forse minimamente per la comunicazione tramite telefono. Noi italiani fra l’altro siamo uno dei popoli che più amano il telefonino. Oggi sono tanti i servizi che offre un telefono cellulare meglio conosciuto con il nome di smartphone. Possiamo dire che con un moderno telefono puoi fare quasi di tutto, dalle foto all’ascolto di musica, puoi gustare bei film, puoi telefonare, interrogare internet e tanto altro. Purtroppo l’uso indiscriminato del cellulare starebbe portando ad alcune problematiche tipiche del nostro tempo come la mancanza di comunicazione tradizionale, vocale e personale e soprattutto l’uso eccessivo del telefono si è sempre detto che potrebbe portare ad una certa tipologia tumorale che implicherebbe il cervello dato che l’avvicinamento del dispositivo all’orecchio, durante la conversazione, scalderebbe il cervello tramite le onde RF quindi a lungo andare potrebbe portare a gravi problematiche. Questo almeno è quanto hanno fino ad oggi sostenuto gli esperti in materia tanto da obbligare le case costruttrici di telefoni a specificare (sulle istruzioni) che l’uso indiscriminato dell’apparecchio cellulare potrebbe nuocere alla salute. Proprio oggi tuttavia stando a questa news sembrerebbe che al contrario i telefonini non siano la causa del tumore al cervello. Una notizia che verrebbe dall’Australia avrebbe a convalida una nuova analisi su 16.800 casi di tumore cerebrale registrati dal 1980. Uno studio guidato dall’ Australian Radiation and Nuclear Safety Agency (Arpansa) in seguito pubblicato sulla rivista BMJ Open escluderebbe qualsiasi legame fra la rapida diffusione della telefonia mobile e l’incidenza dei tumori al cervello. “I tassi di tumori cerebrali sono rimasti piuttosto stabili nei decenni e non sono aumentati tipi specifici di tumori cerebrali” specificherebbe il responsabile della ricerca mirata ed esperto di radiologia Ken Karipidis dell’Arpansa. Lo studio sulla pericolosità dei dispositivi cellulari sarebbe stato finanziato dal National Healt and Medical Research e confermerebbe appunto che il tumore al cervello analizzando i pazienti sarebbe restato stabile fra il 1982 ed il 2013, uno spazio di tempo non indifferente. Fra i 16.800 pazienti australiani sotto analisi si sarebbe compresa un’età fra i 20 ed i 59 anni. I ricercatori addetti al test avrebbero tenuto conto anche del tipo di tumore e della sua posizione. Fra il 1993 ed il 2002 sarebbe stato identificato un aumento n nei casi di glioblastoma, tuttavia grazie alla tecnologia MRI si pensa che sia dovuto a miglioramenti diagnostici. Ecco le dichiarazioni degli esperti: – “Non vi sono stati aumenti in alcun tipo di tumore, inclusi il glioma e il glioblastoma, durante il periodo di sostanziale uso dei cellulari dal 2003 al 2013”, scrive Karipidis. “Non vi è stato aumento di gliomi del lobo temporale, che è la posizione più esposta, durante il periodo di uso sostanziale di telefoni mobili”. Un problema potrebbero darlo i cellulari moderni certamente sempre più potenti ? Secondo i ricercatori australiani, nonostante i cellulari siano sempre più potenti, le radiazioni resterebbero indicativamente della stessa intensità. Lo studio al contrario metterebbe in evidenza che l’esposizione più forte alle famigerate radiazioni da telefono cellulare sarebbe stata evidenziata nel periodo dei dispositivi analogici data la presenza di poche antenne deputate alla trasmissione cellulare. Stando sempre allo studio le nuove reti 5G non dovrebbero destare molta preoccupazione pur promettendo una migliore performance. Possiamo dire che questo articolo ci porti un po’ di sollievo e di ottimismo considerando che la maggior parte delle giovani generazioni utilizzano con molta, forse troppa disinvoltura lo smartphone, tuttavia trattandosi della nostra pelle e del nostro cervello raccomanderei bene o male tutti ad avere una certa prudenza sull’uso dei telefoni cellulari, forse sarebbe meglio utilizzarli un po’ meno e ritornare alle relazioni interpersonali classiche, quelle di un tempo, abitudine che porterebbe certamente dei miglioramenti nelle relazioni interpersonali. Per quanto mi riguarda (forse sarà un eccesso di prudenza) nonostante il test australiano sia certamente serio e certamente valido penso che sull’uso dei telefoni cellulari “fidarsi sia buona cosa ma non fidarsi sia la scelta migliore”, non vorrei che con il passare degli anni e con il crescere della ricerca scientifica altri nuovi studi confutassero (come talvolta accade) i precedenti.

  20. Hello would you mind stating which blog platform you’re working with?

    The reason I ask is because your design seems different then most blogs
    and I’m looking for something completely unique.
