Temporal and spatial variability of personal exposure to radio frequency electromagnetic fields

摘要: BACKGROUND: Little is known about the population's exposure to radio frequency electromagnetic fields (RF-EMF) in industrialized countries. OBJECTIVES: To examine levels of and importance different RF-EMF sources settings a sample volunteers living Swiss city. METHODS: 166 from Basel, Switzerland, was measured with personal meters (exposimeters). Participants carried an exposimeter for 1 week (two separate weeks 32 participants) completed activity diary. Mean values were calculated using robust regression on order statistics (ROS) method. RESULTS: weekly all 0.13 mW/m(2) (0.22 V/m) (range individual means 0.014-0.881 mW/m(2)). Exposure mainly due mobile phone base stations (32.0%), handsets (29.1%) digital enhanced cordless telecommunications (DECT) phones (22.7%). Persons owning DECT (total mean 0.15 mW/m(2)) or (0.14 exposed more than those not (0.10 highest trains (1.16 mW/m(2)), airports (0.74 tramways buses (0.36 higher during daytime (0.16 nighttime (0.08 The Spearman correlation coefficient between first second 0.61. CONCLUSIONS: varied considerably persons locations but fairly consistent within persons. Mobile handsets, important urban Switzerland.
