That is not good. Microwaves are non ionizing; but they are known to cause cataracts and tissue heating at high doses. A microwave of recent vintage is putting out several hundred watts. Don't mess around unless you don't much fancy your eyes.
Several "hundred" watts? Mine is rated at 1800W.
And yes, microwaves are dangerous for multiple reasons, not the least of which is that they can make men sterile (but probably only if you give your junk a good does of em).
Long story short, the door of a microwave has a little metal grid embedded in it. The grid is porous, but the pores are specifically sized to be less than 1/4 of the wavelength of the radiation emitted by the microwave (2450 MHz=~12cm). Because the pores are less than 1/4 of the wavelength, the screen acts as a perfect reflector to the 2.45Ghz radiation emitted. Thus, little radiation excapes the microwave whent he door is closed.
That said, with the door open, microwaves will escape from the oven to a much greater degree than is considered safe. Do the smart thing and replace it.
