Elf magnetic fields, transients and TWA metrics.
International Workshop on Exposure Metrics and Dosimetry for EMF Epidemiology. Chilton, GBR, 1998/09/07.
Residential measurements of ambient power frequency magnetic fields may serve as surrogates for personal exposures.
There are few data available, however, to determine how far back in time this surrogacy holds.
A limited amount of research on residential transients suggests that, all other factors being equivalent, larger transients may propagate within VHCC neighbourhoods than within LCC neighbourhoods.
However, the presence of a conductive residential ground pathway also appears to be a potentially important factor associated with residential transient activity.
The use of the TWA metric was prompted by the need for an exposure score simple enough to summarise an individual's exposure over a prior interval, yet specific to the agent of concern, namely the power frequency magnetic field.
To the extent that the TWA exposure is associated with health outcomes in the absence of bias, including confounding, the TWA metric is important.
