Thanks! I am redo-ing a couple rooms, so I had to remove the already-existent plaster walls which kept the RF levels very low in the house. So my intention is to keep them low as I will probably have to replace the walls with drywall.
I will check out the link you sent and update how things go
Update: I think we might have mixed up EMFs and EMPs. I’m not as concerned about EMPs as I am about high levels of RF radiation.
