Investigation of fetal exposure to electromagnetic waves between 2.45 and 5 GHz during pregnancy
This dosimetry study simulated fetal RF-EMF exposure between 2.45 and 5 GHz during the second trimester, estimating SAR10g in fetal brain and lungs. The presence of a belly-button piercing increased SAR, with maxima reported at 2.45 GHz (16 mW/kg in lungs; 14 mW/kg in brain). Despite these increases, all SAR values were reported to remain below IEEE and ICNIRP limits, while the authors note a precautionary implication regarding metal objects during pregnancy.
Key points
- The study uses nonionizing dosimetry simulations to estimate fetal SAR10g in brain and lungs during second-trimester pregnancy.
- Simulations considered frontal and lateral wave incidence and both vertical and horizontal polarization.
- Fetal SAR increased when a metal object (belly-button piercing) was included in the model.
- The highest reported SAR10g was 16 mW/kg in fetal lungs at 2.45 GHz.
- The maximum reported fetal brain SAR10g was 14 mW/kg at 2.45 GHz.
- All reported SAR values were below IEEE and ICNIRP safety limits.
- The authors conclude metal objects can amplify fetal RF-EMF exposure and suggest precaution during pregnancy.
