The InterPhone |study, which included more than 6,000 people across 13 countries, largely found no link between mobiles and brain tumours, apart from in the 10% of people who used their phones the most, but this could be explained by problems with the study design.
En mayo 2011 la Agencia Internacional para Investigacion del Cancer (IARC, 2011) clasifico como posiblemente carcinogenos a los campos electromagneticos de radio-frecuencia, basandose en el trabajo actualizado de Interphone (Schuz, 2006).
Brandes believes that they need to consider the hormetic model: "A 1-shaped' dose response (decreased risk of brain tumours with low to moderate use; increased risk with excessive use) is highly consistent with the findings of the Interphone Study Group."
* Non-ionizing radiation as from mobile phones (radiofrequency) or power lines (extremely low-frequency); although little evidence for carcinogenicity, the possible effects of long-term heavy use of mobile phones requires further investigation due to widespread use in population (IARC 2011, INTERPHONE Study Group 2010);
To reduce the noise, the excitation frequencies need to be carefully selected to avoid conflict with the frequencies and harmonics of the electric locomotives' return current, track circuit working current, and railway wireless interphone broadcasting.

The results of the Interphone, an inter-national case-control study to assess the brain tumor risk in relation to mobile telephone use, reveals no overall increase in risk of glioma or meningioma but there were suggestions of an increased risk of glioma at the highest exposure levels (30 minutes per day of cell phone use for 8-10 years) and ipsilateral exposures (ICNIRP, 2011).
Different tests like levelling, door operation, ride quality, operation of buttons, signal fixtures, door sensors, interphone, alarm, and emergency landing device are also carried out.
