Past EMF exposure why folks need to log over long periods...
Three days after metering data collection in uT (Tesla Units) the daily above 1.5 uT was consistent exposure of a period of 3600 seconds or 1 hour. The following 8 days up to today has no longer exhibited this phenomenon.
I also have metered unannounced last year the steady frequency of this daily phenomena for about over a week, however measured in mili-Gauss
This is all below 20hz in the ELF / EMF radiation.
