Hardell L, Nilsson M. High Radiofrequency Radiation in the Surroundings of 10 Schools in Örebro, Sweden. Fortune Journal of Health Sciences. 8 (2025): 306-310.
Abstract
In Sweden as well as in many other countries the fifth generation, 5G, for wireless communication is rolled-out since 2019/2020. This has caused increasing environmental exposure to radiofrequency (RF) radiation. Children and adolescents are especially vulnerable to RF radiation. Exposure sources in schools such as Wi-Fi routers, wireless connected mobile phones, and computers may cause high RF-exposure inside the schools but also outside sources, such as mobile phone base stations, may contribute significantly. In this study outside environmental exposure to RF radiation from 4G and 5G base stations was measured in October 2024 in close proximity to 10 schools in Sweden. The maximum levels ranged from 10,716 to 68,452 μ/m2. These levels far exceed the EUROPAEM EMF guidelines for daytime RF radiation exposure 10-1,000 μW/m2, nighttime 1-100 μW/m2, and for sensitive persons 0.1-10 μW/m2.
Excerpts
The measurements were made with the Narda broadband field meter NBM-550, with the probe EF-1891, measuring frequencies between 3 MHz-18 GHz and measurement range 0.6 V/m (955 μW/m2) to 65 V/m (11,206,897 μW/m2). This meter shows results in root mean square (RMS) for both minimum, maximum and average RF radiation level. The frequencies used for 5G in city environments in Sweden are in general around 3.5 GHz while frequencies used for 4G are primarily around 2.6 GHz (https://www.induo.com/b/lte-band-mobilt-bredband/)....
The Narda meter RMS results were considerably lower than Safe and Sound [Pro 2] maximum peak exposure values. As one example, at two different spots, the Safe and Sound meter showed max peak levels of 749,000 μW/m 2 (sleeping room, desk, daughter) and 504,000 μW/m2 (sleeping room, pillow, daughter). The Narda RMS maximum levels at the same spots were 137,889 μW/m2 and 88,616 μW/m2, respectively (22). Both measurements were made at the same time.
