https://en.wikipedia.org/wiki/Electr...y_by_frequencyApart from some suspicion that the electromagnetic fields emitted by mobile phones may be responsible for an increased risk of glioma and acoustic neuroma, the fields otherwise pose no risk to human health. This designation of mobile phone signals as "possibly carcinogenic" by the World Health Organization (WHO) (e.g. it's IARC, see below) has often been misinterpreted as indicating that of some measure of risk has been observed – however the designation indicates only that the possibility could not be conclusively ruled out using the available data.
In 2011, International Agency for Research on Cancer (IARC) classified mobile phone radiation as Group 2B – possibly carcinogenic (not Group 2A – probably carcinogenic – nor the dangerous Group 1). That means that there "could be some risk" of carcinogenicity, so additional research into the long-term, heavy use of mobile phones needs to be conducted. The WHO added in June 2011 that "to date, no adverse health effects have been established as being caused by mobile phone use", a point they reiterated in October 2014.
Básicamente dice que "puede ser" porque no se puede decir que no. O sea, son todas especulaciones. Ni siquiera se sabe que la probabilidad que inventaste exista.
