This is probably a stupid question, but when you have the microwave
going and you disable the door open switch so the microwave doesnt go
off when you open the door while its running what happens?

Not a very smart thing to do, but.....

There's an issue of distance. At a couple of feet, you're likely to
feel
warmth. Closer, and you will sense the RF as heat ranging somewhere
from
really hot to boiling the moisture and fat in your body. At about 4
feet
from the opening of the waveguide, the levels are down to about 5
mw/cm3,
which is the limit for a "controlled environment" Your eyes, and other
"enclosed, fluid filled" organs are most sensitive. Short of having
your
head in the oven, it's likely that you'll move away from it before
anything really serious happens, as it will feel like you're in ....
well, an oven. I've read further down in the thread, and cancer was
mentioned. While RF energy can cause damage as a result of exposure,
cancer is NOT one of the results.

The other half of the equation is the electronic control panel for the
oven. Exposing the panel to a bunch of RF from an open door oven is
likely to give it a serious headache, and probably will put it to
sleep,
shutting down the RF, but, maybe not.


Cataracts can occur at very low exposure rates!!!

Most people probably wouldn't experiment with their shiny new push
button
microwave, more likely they'd wire up the interlock on an old manual
oven
which would be easier to tamper with and less likely to fail due to RF
energy!
Both very true....
High levels of RF can pretty much instantly predispose you to developing
cataracts. Cancer is not one of the after effects under any circumstances.
Getting blasted with high level RF is not a good thing.

Not meaning to argue, but I know of people exposed to cellular frequencies
due to high phone usage (back years ago when analog was the technology) who
did contract skin cancer of the ear. I don't think that the jury is
completely in on the rf link to cancer. I do know that statistics show that
people exposed to high doses of magnetic fields have higher incidences of
leukemia. Again, the jury is still out. I think there is a lot to research
here. Anyway, just my 2 cents worth.
