Intensity = Field Strength

There is a “biological window” of electromagnetic intensities to which the body responds best .
Research of Goodman and Blank: Cells express a cell-preserving gene at 7-8 micro-Tesla rather then stronger fields above 70 micro-Tesla .
Diagnostic systems such as an MRI use field strength of 1.5 – 3 Tesla = 50.000 – 100.000 times stronger .
