 How different it is?  The heat is genrated by absorption of 
electro-meganetic frequency, am I right? X-ray, gama, beta, alpha ray?, 
UV, VIS, Infrared. What is the different of microwave from those 
frequency in terms of cause of "poisoning"?

You are actually eating "modified" protein everyday!!! Heating, fast 
electron-processing of food all involve free-radical generation but water 
quenching them rapidly.
