Comparison Between Broadband and Personal Exposimeter Measurements for EMF Exposure Map Development Using Evolutionary Programming
This exposure-assessment study compares RF-EMF exposure maps produced using a broadband meter versus a personal exposimeter and aims to correct personal exposimeter readings to match broadband-based maps. The authors report that LOS/NLOS-specific correction factors reduce discrepancies, particularly improving LOS measurements affected by body shielding. A genetic algorithm is used to optimize correction factors and support scalable urban exposure mapping, with the authors noting that additional validation in other environments is needed.
Key points
- Compares RF-EMF exposure mapping using a broadband meter (NARDA EMR-300) and a personal exposimeter (Satimo EME Spy 140).
- Focuses on deriving correction factors to make personal exposimeter-based maps equivalent to broadband meter maps.
- Reports that LOS/NLOS-specific corrections reduce error between devices and improve exposimeter accuracy.
- Notes underestimation by the personal exposimeter in LOS conditions, attributed to body shielding effects.
- Uses a genetic algorithm to optimize proportionality factors for LOS versus NLOS scenarios.
- Generates spatial exposure maps using kriging interpolation.
- Concludes that spot measurements from either device can be practical proxies for assessing personal RF-EMF exposure, with corrections improving reliability.
- States that further validation across different environments is needed to strengthen the correction models.
