You're correct, i should have thought of that beforehand because so many people do it. But i'm not so stupid as to open the microwave like that because i know what radiation does to the body. I spend my life working with enough radiation as it is and i don't need that little addition. Three minutes in a microwave would kill you! Every time you open that door when it's running you expose yourself to .30 of a second of powerful microwave radiation at a distance of 2 feet. Do that thousands of times over, over a period of years and you increase your chances of getting cancer a thousandfold. Microwaves haven't been around long enough so they just don't have the statistics yet. Please, before anyone tries to compare this to using a cell phone please do your homework.
