Domestic supply substation 40ft away is a non-event.
About a mile from me a pub & house are within 100ft of a power station
Tx the size of a house.
- The only ill effects they find are the perpetual rain and incredible
frost displays caused by the output from 8 cooling towers, combining
with fog from the nearby estuary.
- The bigger effect in the area is likely to be from its coal burning
- with old stations the arsenic concentrations were higher in the
prevailing wind fallout path. Arsenic is known to reduce resistance to
viruses (the outfall from the chimney will not drop on them as they
are basically in the carpark).
In the UK it is not unknown to get a Tx stuck virtually in your front
garden with no building around it. Very ugly and more typical of
industrial locations (AEI 1MVA supplying adjacent small industrial
units). So you are some distance away.
The thing I would not like is 132-400kV overhead lines directly over a
house. Hold up a fluorescent stick light bulb for the energy
radiation. The radiation from holding a mobile phone aerial against
your head is far greater than your substation.
A lot of nuclear exposure research found whilst dosage is
accumulative, small dosages have disproportionately LESS effect than
high levels. It is quite possible the same applies to EM radiation.
Away from the heat of a nuke, sheltered from the immediate radiation,
a nuke is less horrific than people are led to believe. The problem is
the wind direction in theatre re wind borne fallout on your troops
