I'll be the boring guy that points out that microwaves wouldn't irradiate you, nor give you radiation sickness. They are somewhat more powerful than radio waves, but less powerful than infrared radiation.

They do not cause cancer. Pretty much the most dangerous effect would be your skin and some outer muscles cooking. Or cataracts in your eyes. That's why people always tell you not to get close to the microwave screen and stare through it.
Which, by the way, that screen is pretty much perfect at stopping the waves. They have a wavelength of several inches.
So, uh... yea I'd have tons of cataracts and perhaps a couple minor burns. I usually only take things out when I'm done heating them, and I doubt I'd be stupid enough to leave an oven on that was actively burning my muscles if I was done cooking the food.
