How Do I Know There Are No Leaks ? (Microwaves)
« on: 27/09/2007 19:34:30 »
Dear Microwavermental Mavericks,

This is a Microwave Oven:



Nice isn't it ?..Notice how well closed and inside the radiation is ?

..and this is Mike !..say Hello Mike !!   Mike says 'Hello'...he's giving ewe a Micro-wave !!...

How do I know that none of Mike's waves are leaking out from his Microwave Oven home ?
Is there some sort of alerting system ?...


Sometimes we like to peer into the oven watching Mike wave at us ...so..if there was a leak would Mike hurt us ?

I have often wondered about that!

No (only if if its heating effect was significant)
Hold your hand close to any places where you suspect there is a leak, If you feel it is getting hot start worrying.
If you want a more sensitive test replace hand with a small transistor radio

THANKS SYPRUM.


Why would I use a transistor radio ?...would I pick up some hot tunes ?

Probably cause static!

Even though the small transistor radio would be tuned to the normal MF broadcast bands any significant amount of 2450 MHz radiation would upset the operation of the transistors and be noticeable.
Nice looking cooker, does it incorporate a grill?.

THANK EWE AGAIN SYHPRUM.

I will indeed try the tranny next to the oven.

I would love to be able to answer ewe regarding the specs of that particular model but all I did was grab a picture off the net......... And, LOL :)..ewe've had me trawling the Panasonic website for the last few minutes for that particular model  and I just can't find it !! *le sulk*...sorry !!...but at least I tried !!

If a microwave oven were to leak it would be bery dangerous and could cause blindness if you gazed into a crack from which microwave energy was leaking.  Ideally the microwaves should be contained within a solid metal container but the need to ave a door prevents this.  Most peoples first idea would be let us ensure that the microwaves can leak out by having good metal to metal contacts round the edge of the door.  OK this would work, but it would be quite easy to damage them and a small slot would be a very nasty leak.  However there is another way  it is by a process known in  microwave engineering circles as a choke flange.  it makes use of the fact that microwave ovens are always used at a precisely defined frequency of 2450 MHz  if you look at the door  you will see a close contact and a little groove around it.  this is effectivley a microwave filter that makes the open circuit at the edge of the door look like a perfect conducter at the inside of the cavity and effectively prevents any microwaves leking out very reliably.

I seen one similar a target. It had the stainless steel outer Shell. It is sleek.

BTW The radio sounds as if it acts like a Geiger counter! Is that correct?
