Abstract

Long-term exposure to physical agents can be detrimental to children due to their vulnerability. This study aimed to assess and compare the electromagnetic field (EMF) exposure level around the kindergartens from the underground transmission line (UGTL). We investigated randomly selected 24 kindergartens based on the location of the UGTL. The EMF emission levels were measured using an EMDEX II (Electric and Magnetic Digital Exposure Meter). The maximum mean value of the EMF emission level was 13.5 mG around the kindergartens and 17.7 mG from the point of UGTL to kindergartens. EMF emission level around the kindergartens was significantly associated with the location of the UGTL ( = -7.35, < 0.001). These estimates are not trivial, as long-term exposure to EMF among kindergarten children can lead to different health problems. Routine monitoring of EMF emission levels is recommended including the awareness of EMF exposure to public citizens.

Main findings

In 24 randomly selected kindergartens, the maximum mean EMF emission level was reported as 13.5 mG around kindergartens and 17.7 mG from the UGTL point to kindergartens. EMF emission level around kindergartens was significantly associated with UGTL location (β = -7.35, p < 0.001).

Outcomes measured

  • Magnetic field (EMF) emission level (mG) around kindergartens
  • Association of EMF level with UGTL location

Limitations

  • No health outcomes were measured; health implications are stated as concern rather than observed effects.
  • Frequency and other exposure parameters beyond mG are not reported in the abstract.
  • Measurement protocol details (timing, duration, distance metrics) are not provided in the abstract.
