## 5 Conclusions  
This study reviewed 86 scientific works on personal exposure to RF-EMF that conducted measurements through spot measurements and/or using different methods (mixed method) combining spot measurements, personal measurements with volunteers or with trained researchers, spatiotemporal exposure measurements and in some cases using model predictions. In addition to the exposure measurement studies, we want to refer to a study recently published by [PERSON] [143] in which electromagnetic fields produced by \"smart\" devices used daily in a modern \"smart\" home are measured. It is interesting to see the activity of these EMFs in different periods of time while they are used. This study has not been included in this review because although specific measures have been taken, exposure to these fields has not been measured. As far as we know, today, despite the different methodologies used, the results are comparable with international reference levels and comparable between microenvironments and countries; although it is true that some values are higher than others, they are still lower than these reference levels. The minimum average was measured in Palestine at 0.0600 \(\upmu\)W/m\({}^{2}\) in 2017, and the maximum average was measured in Norway at 200,000 \(\upmu\)W/m\({}^{2}\) in 2022, equivalent to 0.200 W/m\({}^{2}\), far below the permitted international reference levels. During the development of this work, we have seen that the statistical data confirm that the exposure levels to RF-EMF are much lower than the maximum levels allowed in the ICNIRP guidelines, both for the general public scenario (10 W/m\({}^{2}\)) and for the occupational scenario (50 W/m\({}^{2}\)). However, these values can change over time, considering the new 5G technologies introduced everywhere right at this moment, so it is recommended to stay vigilant and continue expanding research in this field. As previously indicated, with this work, we want to help researchers scrutinize this field with a review that classifies, orders, and synthesizes, thus making a reference for future research and comparisons. We believe that in the future, some research areas may be prioritized in the field of radiofrequency electromagnetic exposure fields: exploring new measurement devices, such as the use of sensors that have already begun to be used to monitor RF-EMF [111], as well as carrying out longitudinal studies to evaluate possible long-term effects. We want to highlight that in this society in which we currently live, in which we are always immersed in a sea of electromagnetic waves, the importance of clear and effective communication of the possible risks associated with RF-EMF exposure, as well as the need to educate the public on how to minimize exposure in everyday environments.
