Do you apply sunscreen every time you go out in the sun? If not why not? That is far more damaging radiation than you will get from a microwave oven.

If the measurer shows ANYTHING at switched off device, it means it is not measuring a MW range but a whole range from 1 Hz until whoknows 10 GHz. And 50Hz is those source giving a rather strong impact. Only comparing the ICNIRP1998 with ICNIRP2010 You ought to see that at 50Hz the "norm" is 5 kV/m whilst at 2,4 GHz it stays 61 V/m. Therefore "superwide" range detectors are nonsense. Excepy if they have a function of spectral distribution analize. Actually, even if You have no better sensor, You may take in account only alone power density measure. At 2,4 GHz it ought not overstep the 10 W/m2, and that is more than sure that 50Hz cannot even to think about such irradiation - or W/m2 are coming exclusively from MW owens. If it is over, run and never come back. If it is under, and only E and H are large, just organize the appropriate grounding/earthing. For 50Hz its rather effective. Cabling may exert surprizingly much, even 1-2 kV/m and 200-500 microTeslas over active power cables of large power, while 100 is the legal maximum. But few steps to or forth and it normalizes in contrast of MW where sometimes even 10 steps are not enough if the few mm gap had been formed. Just if ONE of sizes are larger than 8cm then other size may be as small as one want, but the vawe is capable to eak through. Therefore the doors MUST have very gap-less tightenings.
 
Neon bulbs and grapes will not work. The maximum allowed leakage is 5 milliwatts per square centimeter at 2 inches from the door. It would take a lot more than that to warm a grape or light a neon lamp.
Amazon has meters for sale for less than $50 that would probably be adequate.

I rather like @Reloadron's recommendation of a NEON lamp. You don't have to wait for the grape to warm. Meanwhile your eyeballs are also getting warmer. With the lamp you know from the moment the leak is detected.

I agree as to "allowable leakage" but isn't the idea to detect energy from a flawed microwave oven? Additionally wouldn't the leakage in a flawed unit be a function of the power in? I haven't a clue the power level of restaurant grade microwave ovens. Pure guess maybe greater than or around 1.2 KW?

I also have to agree with a turned off microwave is not going to release any energy as was mentioned so there is more to this. Make or buy a cheap detector which is frequency specific and get some indications of what is actually going on.

Finally the old classic Gerbil in the Microwave comes to mind.

Purchase a 357 or 44 magnum, point at said microwave, AIM carefully, pull trigger.
said microwave is dead.... No more problems.
Sounds like someone has put it in your mind that microwaves are "BAD"
Don't worry the big asteroid is on its way!
I would go with "post #5" from Dodgydave
You should be safe then.

To be devils advocate for a moment; the OP could be in a country where controls are not as tight as they are in the USA, Canada, Europe, etc.. and perhaps he has legitimate reason for concern that devices in general are not made to the same safety standards as the rest of the world. That doesn't mean he has a real problem, but perhaps his general concern is not unjustified?

I have to advise the use of proper hearing protection.

OK I guess we have to consider that possibility but I still don't quite get how a microwave oven while turned off can emit any microwave RF radiation?

I also find that there is a device called a RF jammer. How would I build this device aimed at microwaves?
