How much radiation are schools exposed to?

May 23,2025

Given the amount of time that children spend at schools, it’s important to know just how much radiation schools are exposed to.

A new study by Professor Lennart Hardell and Mona Nilsson sheds light on this important question.

The researchers conducted measurements at the boundary of ten schools in the Swedish city of Örebro and found levels of exposure far higher than recommended for health and safety.

While the levels of radiation varied in different locations, maximum levels measured between 10,716 and 68,452 µW/m2. As Hardell and Nilsson point out, these levels are above those of the EUROPAEM EMF guidelines which recommend that exposures should be:

  • 10 – 1,000 µW/m2 during the day
  • 1 – 100 µW/m2 during the night
  • 0.1 – 10 µW/m2 for people who are sensitive.

The levels at the schools are, however, lower than the limits of the International Commission of NonIonizing Radiation Protection (ICNIRP) which Hardell and Nilsson suggest do not necessarily protect health. They say, ‘Those limits have been adopted by most countries although they only protect against thermal acute effects observed at very high intensities within an hour in animal laboratory experiments.’

Hardell and Nilsson say that children are more vulnerable to radiofrequency radiation than are adults. ‘This is due to the fact that their cells are rapidly dividing and the organ systems are immature. RF radiation exposure may have adverse neurobehavioral effects and also negative impact on cognition.’

They refer to their previous studies where they’ve found adverse effects on exposed children. ‘Most prevalent were negative impact on sleep, fatigue and headache,’ they said.

The authors point out that it’s not just external sources of exposure, such as those they measured in this study, that affect children in the classrooms. ‘a significant portion of children’s exposure to RF radiation may be due to exposure sources inside the school such as Wi-Fi routers, wireless connected computers, and mobile phones.’

Nevertheless, the results of this study raise issues that should be concern to all of us who care about our children’s health.

‘Our results ofRF radiationmeasurements indicate that the exposure to RF-radiation from nearby 4G and 5G base stations in the surroundings of 10 schools in Sweden is high. These levels may cause increased risks of both short term and long term negative effects on children’s health,’ the authors say.
