I'm a product safety engineer. This discussion is based upon a safety standard specifying a limit for the accessible electric field strength.
Doug Smith said: "These days we think 10 V/m is dangerous." See: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3553569/ This article (with scholarly research annotated) essentially says that we don't know the effects of electric and magnetic fields on the body. It cites 0.4 uT (>100 V/m) as a potential limit for children. Doug goes on to cite his experience with exposure to 100 times 100 V/m with no ill effects. I wonder how the standards writers came up with limiting field strength when there is no definitive bodily injury? Probably BOGSAT.
