Abstract

The surrounding outdoor environment for new development has a big effect on the indoor quality of life. The main aim of this work was to determine the suitability of the area for building new schools with reference to electromagnetic field (EMF) effects. The specific objective of this study was to detect the safe distance from the EMF posed by the high-tension overhead power lines in the vicinity of the specified area. The measurements were taken for both the electric and magnetic fields in different months in order to detect the highest EMF levels during the peak power load season. EMDEX II with E-probe and EMDEX II with Linda were used for the measurements. These instruments were all calibrated by ENERTECH Company in USA. The EMF associated with high tension transmission lines that surrounded the proposed site has to be below 0.2 μT (Italian EMF regulations are the most suitable regulations for the establishment of schools in Kuwait). The safety clearance distance from the existing 300-kV high-tension power line has been assigned as 200 m and from other existing 132-kV high-tension power line was 50 m. The proposed site with its predefined boundaries has a magnetic field below the Italian EMF regulations for the establishment of new schools.

Main findings

Electric and magnetic field measurements around high-tension transmission lines were used to assess suitability of a proposed school site. The authors report a safety clearance distance of 200 m from an existing 300-kV line and 50 m from an existing 132-kV line, and that the proposed site’s magnetic field was below the Italian regulation level of 0.2 μT for establishing new schools.

Outcomes measured

Electric field levels
Magnetic field levels
Safety clearance distance for school siting relative to power lines
Compliance with Italian EMF regulation threshold (0.2 μT)

Limitations

No health outcomes were measured; the study focuses on environmental EMF levels and regulatory compliance.
Frequency of the fields was not stated in the abstract.
No quantitative measurement results (e.g., maximum/mean field values) were provided in the abstract.
Study location and generalizability beyond the specified site are not detailed in the abstract.
