We are exposed to multiple electromagnetic fields (EMFs): low-frequency fields from power lines and electrical and electronic equipment, and radio-frequency radiation from wireless devices such as mobile phones and wireless Internet antennas. We don´t seem to feel them, but they´re all around us, and they even interact with our own electromagnetic fields. Potential health risks deserve to be investigated and reported on the eve of what promises to transform the planet thanks to a new paradigm of unstoppable and constant connectivity.
