Public Engagement with Science in Everyday Life: Perceptions of Wi-Fi Radiation Risks in Schools


Wi-Fi radiation is a type of radio frequency electromagnetic radiation (RF-EMR) that refers to the transfer of energy by radio waves. Nowadays, exposure to RF radiation is widespread including wireless internet connection (Wi-Fi) routers and cell phones. The proliferation of devices emitting RF radiation has entailed some public and media-generated controversy, although scientific evidence has not pointed to the existence of risk. Using the theoretical perspectives of science literacy, public engagement with science, and science media literacy, this work examines public engagement with science-related media reports in a context involving risk. A qualitative design was followed to address multiple viewpoints including an analysis of an authentic primetime TV program concerning the risks of Wi-Fi, its messages, and frames, solicited a public response to the coverage via interviews and decision-making simulation (n = 20), and unsolicited public response based on social media discussions (n = 315 comments). Our findings suggest that a lack of relevant scientific knowledge does not seem to be related to participants’ general scientific literacy among people with higher education. Moreover, interviewees did not place much emphasis on having adequate knowledge in making their decision. These findings emphasize that we need to expand our understanding of the different ways that make scientific knowledge relevant when making decisions on scientific issues that relate directly to everyday life.

    Wi-Fi is a radio frequency local area connection technology in the 5–10-cm wavelength range. Within the non-ionizing (NIR) spectrum, we find RF (radio frequency) and ELF (extremely low frequencies). Prevalently used appliances all emit radiation in the RF spectrum; these include cell phones and towers, microwaves, and Wi-Fi routers. An example for a source of ELF is power supply lines.

    As opposed to ionizing radiation (IR) which has enough energy to break chemical bonds and remove electrons.

  3. 3.

    Percentages were calculated based on data published in and on information provided on the ICT program website: (retrieved in December 2018).

    337,600 households throughout. As an illustration of the program’s popularity, on that same evening, a European soccer match was viewed in 267,200 households and a well-known travel and cooking show was viewed in 278,600 households on competing channels:

  6. 6.

    Physics curriculum in the 1990s (when most of our interviewees were in school) was mostly limited to self-selected teens who studied high level physics (in high school), and electromagnetic radiation was not included in other curriculum.

Appendix 1. Scenario

“Your child’s school is about to join the National ICT Program. The children will receive tablet computers which are connected to the internet via Wi-Fi, and they will use them daily during lessons. Some parents are worried that the radiation may have health implications, while others say there is no danger, and there is a great educational benefit in the program. Tomorrow there will be a special parents’ meeting to vote about the use of Wi-Fi in the school, and you have to decide how to vote using any available resources you might have in everyday life (including searching the internet and consulting other people). First, please watch this TV program which was broadcast recently on national TV. Then you’ll have another 30 minutes to look for additional information. You don’t have to use all of the time and can tell me whenever you make your decision.”
