Checking the microwave for microwave RF leakage

Can you check your microwave with standard RF measurement tools, well not really unless it has a special “Microwave leakage” button on the tester.

The New Zealand / Australia standard for testing microwave oven, this has to be done after every repair to a microwave oven. [along with earth to earth continuity resistance measurements and as well as Phase & Neutral pins of the female plug to the earth pin for high Voltage resistance leakage testing.]

The Microwave RF limits are;
or 5 mW/cm^2
(where ^2 is equal to squared)
At about 50 mm distance from the microwave surface.

This relates to about,
97, 082 mW/m
97 V/m
500,000 mW/m^2
500,000,000 µW/m^2
0.005 W/cm^2

The Service industry uses a specially designed “microwave leakage tester.”

Hi Eric
I have used a standard RF meter (Acousticom 2) to ‘test’ microwave ovens for leakage. But in relation to general microwave levels, not specifically to industry standards for ovens. In all cases I have found leakage at levels which would be a serious cause for concern if they came from a wifi router or a cordless phone. So I advise people to stay out of the kitchen when the oven is running.I realise this is a slightly different perspective.
97 v/M sounds very high. Well beyond the range of any of my meters.

Yes Peter, It is hard to say more until these RF meters come out with a “Microwave test” selection so they can test at stronger levels without going off the scale like my one does, or one could get a set length of string and sellotape one end to the microwave to get idea on a set distance, so one can get a better idea of the reading they get, or simply get a microwave leakage tester from ebay. I have tested many microwaves and never found one that goes too high, but then all the microwaves look in good condition, for example the magnetron or electronics fail before the door seal or hinges.

Not only am I one step down from a registered electrician, I am also a licensed amateur radio operator, a amateur radio friend showed me his radio that was tuned to 2.45 GHz, as he lived on a slight hill, he scanned it across the city below and showed the whole city is a wash with 2.45 GHz radiation, he added the signal is much stronger at meal time when most people use their microwave ovens.

Personally I have given up on eating food that has been especially manufactured for heating in the microwave, and now I freak out when I am at a friends house and they ask me if I what a drink or something to eat, next minute they are poking something in the microwave to heat it. So now I say “I do not eat between meals and I stopped drinking hot drinks because I have mercury teeth fillings and only drink water.”

There seems to be three groups, people like you and me that see the dangers of modern technology and why cancer has gone rampant and out of control, but there are others that like the warmth of having their head in the sand all the time & the third group that say oh well everyone gets cancer today, so you get cancer, well you just get cancer there is nothing you can do about it. They are the ones wrecking our health with all their things like WiFi, another reason why I am keen to get a tee shirt “Kill bedroom Wi-Fi, before you kill our health.” Why have one that says “I love New York” when they live in New Zealand.

As the start of this conversation thread says the standard RF field strength measuring tools used by this group are a lot more sensitive than what the regular microwave test limits are.

So why not think inside the square for increased product range and increased income. Come up with a microwave cabinet & more important a “Faraday curtain” to pull across the door as the microwave is working, to limit and reduce the amount of 2.45 GHz RF been exposed into the kitchen to kitchen users, not too mention 2.45 GHz absorbers such as brick that has been mentioned once to place inside the microwave to use as a load instead of a glass of water when testing microwave ovens. (Otherwise the microwaves goes back into the magnatron and reduces the life of the microwave oven) Then where are the microwave “Faraday safety glasses”? I have recently purchased blue blocking glasses to reduce the blue light given off by modern electronic screens and LED lamps.

I am not a microwave user so do not expect me to spend any money experimenting on making kitchens RF field safer.
