The use of radio frequency sources is very widespread, whether it is in mobile phones, Wi-Fi, Bluetooth, phone antennas, radio and TV, etc., and there is a huge amount of information to find out whether these emissions fall or do not fall within the recommended levels.

In any case, "the levels to which children are exposed need to be properly analysed to be able to conduct epidemiological studies, and for this it is essential to optimize the methodology", pointed out Mara Gallastegi-Bilbao.

She is the author of the work, she wrote up her PhD thesis at the UPV/EHU and is currently working at the Biodonostia Institute.

That is why this work had a triple aim: firstly, by means of spot and personal measurements, to study exposure of 8-year-old children to radio frequencies; secondly, to identify the locations and sources that have the greatest repercussions on the overall calculation of exposure; and finally, to examine whether the assessments obtained through spot measurements could replace personal measurements.

To be able to compare the two methodologies, personal and spot measurements were made during the course of the work.

"In recent years, personal measurements have been on the increase.
