Il comune di Sonogno avrebbe anche fatto a meno del primato che lo vede guidare la classifica dei comuni ticinesi più radioattivi. La graduatoria che vede il paese verzaschese primeggiare in tutto il cantone emerge dallo studio dell'Università di Berna sulla radioattività naturale in Svizzera e i legami con il rischio di tumori nei bambini e nei ragazzi sotto i 16 anni.
La ricerca condotta dall'Istituto di medicina sociale e preventiva ha evidenziato che, come riportato da 20minuti, se in Svizzera vi sono 120 località che presentano valori elevati (oltre i 200 nanosievert) ben 49 si trovano in Ticino (soprattutto in zone montane e collinari) con in testa Sonogno dove il valore è triplo rispetto alla media nazionale.
Lo studio giunge a concludere che i bambini e i ragazzi che vivono in aree con elevati livelli di radiazioni terresti e cosmiche tendenzialmente hanno un rischio maggiore di sviluppare leucemie e tumori al cervello.
