WHAT HAVE WE FOUND?
Regarding the altern electric fields measured with the free potential method the readings were non significant: 0,0 V/m in the plot .
Regarding the altern magnetic fields the readings were slightly significant: 59 nT in the plot.
WHAT SHOULD BE FOUND
Altern electric fields: readings should be below 1,5 V/m and ideally below 0,3 V/m.
Altern magnetic fields: readings should be below 100 nT and ideally below 20 nT.
