“…This first group does not usually perform real-time, in situ measurements, and their exposure data is based on the use of different wireless devices, making simple estimates concerning time (28,31), distance to antennas (29), or mathematical prediction models (36). Secondly, studies that measure in real-time use different protocols and measurement systems (4,6,7,30,34). On the other hand, publications characterizing EMFs aim to observe that the RF-EMF exposures to which the general population is exposed are within the legal limits of each area (37-40).…”
