NOTE: This chart applies mostly to the OLDER Cathode Ray Tube (CRT) monitors, and only somewhat applies to the NEWER LCD or LED flat-screen monitors. Each monitor should be tested, so that you can see whether or NOT there are DETRIMENTAL EMRs, being emitted. Also, there may be other Electromagnetic Field Radiations being emitted, which have NOT been found, NOT being shown on this particular chart.
