There's a microwave near my desk in my office, I'm a little paranoid about being exposed with too much electric magnetic radiation (EMR). If I added a board with tin foil, will that block out the EMR?

There is history of people being affected by nearby faulty microwave ovens. I seem to remember people getting cataracts.
There is a Health & Safety regulation that electrical items at work have to be checked for electrical safety, I would be very surprised if these things would not not have to be tested regularly for microwave leakage. Check with your local H&S Executive.
I don't think tinfoil is going to protect you. Proper maintenance of the microwave cooker is.

depends on how far you are from it and where it actually is facing. The worst case would be if the microwave's face was directly facing you and you were within a couple feet of it. Which would mean that people wouldn't be able to open it.
The body of the microwave does hold the majority of the Emissions, but some does leak out from it. It is all within FCC regulations. Newer microwaves have been made to hold the emissions better. The main thing that the microwaves can affect are your eyes and genitals. Since they are the size of the frequency wavelength. Which is why you should never look directly into one, or hump one while its on and for a long period of time.
In my opinion, you are fine. There are meters that will give you readings but they are expensive. There is the NARDA probe and the Radman personal monitor (The Radman beeps when you are in high levels)
Here are a couple web sites I found with RF absorbing material, I have no idea the amount that it can reduce or how much it costs, but I did a search for "RF absorb material" and this is what I found.

The answer is no because if you are familiar with the way a wave moves and The Doppler Effect. This is that when a wave hits a corner or edge of an object (in this case the board) the wave is dispersed around the board and splits into two waves. It would definitely reduce EMR but not eliminate it

Yes. My (rather old) microwave's instruction book includes a bit about defrosting joints of meat. It says that you can stick small bits of foil over fatty bits which would otherwise get cooked even on defrost settings. (Take care, don't let the bits of foil touch each other.)
I can't see that you've got anything to worry about.
Even when there are holes in a metal screen, they have to be of a significant size in order to let much radiation through. The lower the frequency (i.e. the longer the wavelength) the bigger the hole has to be. There's a metal screen full of holes in the door of your microwave but the holes are small enough for the radiation level passing through to be negligible. Just as well, otherwise you would have a job seeing what's going on inside.

Yes but you need to wrap it around your skull too.

Yes that will work but i do not think necessary
