I can't belive the garbage that people publish, spreading their ignorance around. X-rays are not "energy fields," radio and micro waves are are not "high frequency," and radio waves clearly do not cause thermal damage to our cells. And that's just the errors in two sentences!

Also, based on that paragraph, I am led to believe that the author has no idea how microwaves work. At least read some popular science (HowStuffWorks "Introduction to How Microwave Cooking Works") before you spout your "facts" publicly.
