Environmental RF-EMF exposure levels at kindergartens exceeded personal exposure levels measured on children.

Plain English Summary

Summary written for general audiences

Researchers measured radiofrequency electromagnetic field exposures in kindergarten children in Melbourne, Australia. Measurements covered 16 frequency bands between 88 MHz and 5.8 GHz. The median environmental exposure across all bands was 179 mV/m, while the median personal exposure across all bands was 81 mV/m.

Why This Matters

The study distinguished between environmental exposures, measured at the kindergartens themselves, and personal exposures, measured on the children. For environmental exposures, the three highest contributing sources were GSM 900 MHz downlink at 82 mV/m, UMTS 2100 MHz downlink at 51 mV/m, and GSM 900 MHz uplink at 45 mV/m. For personal exposures, the highest source was GSM 900 MHz downlink at 50 mV/m, followed by UMTS 2100 MHz downlink, GSM 900 MHz uplink, and GSM 1800 MHz downlink each at 20 mV/m. Wi-Fi 2.4 GHz contributed a median environmental exposure of 16 mV/m and a median personal exposure of 9 mV/m.
