[Operational aspects of risk perception in the electromagnetic fields exposition].

Abstract

The increase of electromagnetic fields exposition is being associated with the increase of risk perception in the people exposed due to the uncertainty of the biological and sanitary effects. Research is being carried out on the symptomatology shown by the 45 people living near power-lines in the Benevento area and consequently exposed to electromagnetic fields. The measure of the magnetic and electric field was in the normal range while the people showed most symptoms in the subjective and behavioural sphere. The research findings suggest that risk assessement should take into account the subjectivity of the people exposed as shown in the special questionnaires with the aim of reducing the subjective and behavioural symptomatology for developing a new environmental medicine.

Main findings

In 45 people living near power-lines, measured magnetic and electric fields were reported to be in the normal range, while participants reported symptoms mainly in the subjective and behavioural sphere. The authors suggest risk assessment should consider subjectivity as captured by questionnaires to help reduce subjective/behavioural symptomatology.

Outcomes measured

• Risk perception
• Self-reported symptomatology (subjective and behavioural symptoms)
• Measured magnetic field level
• Measured electric field level

Limitations

• Small sample size (n=45)
• Symptoms described as subjective/behavioural; objective health outcomes not reported in the abstract
• Study design and presence/absence of a comparison group not described
• Exposure measurement details (methods, duration, metrics) not provided

Suggested hubs

• occupational-exposure (0.2)
  Published in an occupational medicine/ergonomics journal, but the described population is residential near power lines rather than workplace exposure.
