Exposure Knowledge and Risk Perception of RF EMF.

Abstract

The presented study is part of the EU-Project Low EMF Exposure Future Networks (LEXNET), which deals among other things with the issue of whether a reduction of the radiofrequency (RF) electro-magnetic fields (EMF) exposure will result in more acceptance of wireless communication networks in the public sphere. We assume that the effects of any reduction of EMF exposure will depend on the subjective link between exposure perception and risk perception (RP). Therefore we evaluated respondents' RP of different RF EMF sources and their subjective knowledge about various exposure characteristics with regard to their impact on potential health risks. The results show that participants are more concerned about base stations than about all other RF EMF sources. Concerning the subjective exposure knowledge the results suggest that people have a quite appropriate impact model. The question how RF EMF RP is actually affected by the knowledge about the various exposure characteristics was tested in a linear regression analysis. The regression indicates that these features - except distance - do influence people's general RF EMF RP. In addition, we analyzed the effect of the quality of exposure knowledge on RF EMF RP of various sources. The results show a tendency that better exposure knowledge leads to higher RP, especially for mobile phones. The study provides empirical support for models of the relationships between exposure perception and RP. It is not the aim to extrapolate these findings to the whole population because the samples are not exactly representative for the general public in the participating countries.

Main findings

Participants reported greater concern about base stations than other RF EMF sources. Regression analyses suggested that most exposure characteristics (except distance) influenced general RF EMF risk perception, and there was a tendency for better exposure knowledge to be associated with higher risk perception, especially for mobile phones.

Outcomes measured

• Risk perception (RP) of RF EMF sources
• Subjective exposure knowledge about exposure characteristics and perceived health risk impact
• Associations between exposure knowledge/exposure characteristics and general RF EMF risk perception

Limitations

• Samples not exactly representative for the general public in the participating countries
• No sample size reported in the provided abstract
• Frequency/SAR/exposure metrics not specified in the provided abstract

Suggested hubs

• who-icnirp (0.2)
  Addresses public risk perception of RF EMF sources relevant to exposure guidelines/communication, but no direct guideline evaluation stated.
