Abstract

Low frequency magnetic fields inside cars Pääkkönen R, Korpinen L. LOW FREQUENCY MAGNETIC FIELDS INSIDE CARS. Radiat Prot Dosimetry. 2019 Nov 7. pii: ncz248. doi: 10.1093/rpd/ncz248. Abstract Magnetic fields were compared inside passenger seats of electric, petrol and hybrid cars. While driving about 5 km in an urban environment, values were recorded and compared between car types. The magnetic flux densities of the cars were less than 2.6 μT. The magnitudes of the magnetic fields of petrol cars and hybrid cars were about the same and slightly lower for electric cars. Based on our measurements, values were less than 3% of the guidelines given for the general population or people using pacemakers. ncbi.nlm.nih.gov

Main findings

Magnetic fields measured inside passenger seats during ~5 km of urban driving were reported as <2.6 µT. Petrol and hybrid cars had about the same magnetic field magnitudes, with slightly lower magnitudes for electric cars. Reported values were <3% of guideline levels for the general population or people using pacemakers.

Outcomes measured

  • Magnetic flux density (µT) inside passenger seats during driving
  • Comparison of magnetic field magnitudes by car type
  • Comparison to guideline levels (general population, pacemaker users)

Limitations

  • Sample size and number of vehicles not stated in the abstract
  • Measurement frequency characteristics and instrumentation not described in the abstract
  • Short driving distance (~5 km) and only urban environment mentioned
