Smartphone-Based Methodology Applied to Electromagnetic Field Exposure Assessment

Area of Science:

• Environmental Science
• Electromagnetics
• Public Health

Background:

• Electromagnetic field (EMF) exposure assessment is crucial for environmental and health studies.
• Traditional EMF measurement methods can be time-consuming and resource-intensive.
• Developing efficient and accessible measurement techniques is an ongoing research priority.

Purpose of the Study:

• To comparatively evaluate the efficacy of smartphone-based electromagnetic field (EMF) measurements against standard broadband meter methods.
• To assess the feasibility of using a smartphone application for large-scale EMF exposure characterization.
• To determine if smartphone measurements can provide proportional and reliable data for comparative studies.

Main Methods:

• Conducted two EMF measurement campaigns across a 1.9 km² university campus.
• Utilized a broadband meter at 20 fixed sites for traditional measurements.
• Employed a smartphone with a dedicated application to record EMF levels at 860 points along a bicycle route.

Main Results:

• A direct proportionality was observed between EMF measurements obtained via the broadband meter and the smartphone app.
• The smartphone-based methodology allowed for characterization of EMF exposure in the study area significantly faster (four times less time) than traditional methods.
• The study validates the use of smartphones for comparative EMF exposure assessments.

Conclusions:

• Smartphone applications offer a viable, efficient, and cost-effective tool for comparative electromagnetic field exposure measurements.
• This approach significantly reduces the time and resources required for environmental EMF characterization.
• The findings support the integration of mobile technology in environmental monitoring and public health research related to EMF exposure.
