What safeguards does a microwave oven have in its design to ensure harmful rays do not leak into the kitchen?

Answer 1

The oven cavity is a "tuned" circuit. It is designed for the most effective use and distribution of the energy. The door mesh, as stated by others is designed to prevent radiation release. The door is also a tuned circuit by virtue of indented design. The door to main cavity dimensions act as a capacitive, and inductive circuit that attenuates the energy level so that very little is allowed to get out. In effect, the door structure is a large resistor that stops the signal flow. .

Answer 2

1. The window has a metal mesh with holes that are 1/4 the wavelength of the microwaves inside. They "trap" the microwaves.

2. The door is indented into the cavity (not flush), so any microwaves reaching the door seam will have a zig-zag path to reach the outside, and not a direct path through a straight seam.
(I hope that was clear)

3. There is a switch located inside the oven, that is not accessible to humans, except via a metal piece attached to the door, so... that only by closing the door will the oven be operational.

4. The cabinet surrounding the cooking cavity is metal, not plastic.

Answer 3

check out how microwaves prepare dinner nutrients (above) and then think of what that very same microwave radiation ought to do on your physique! Microwave leakage is extreme sufficient that the FDA instruments strict limits on it for the producers. yet as quickly as door seals age, leaking has a tendency to exceed those limits, frequently at head point. That’s undesirable information, using fact the microwave ability interior a microwave oven is super! Frequency interior your microwave 2.40 5 BILLION hertz. Frequency shown to start harming the human physique: over 10 hertz. That’s 2.40 5 billion vs. 10 hertz. It doesn’t take very huge leak for the wear to start. (One suitable criminal: becoming older door seals!) the frightening section is which you won’t experience it till the wear is long for the reason that performed. no count number what, you do no longer opt to stand in front of or on the edge of a microwave in operation. risky consequences of microwaves: Weakened immune structures decreased resistance to bacterial and viral infections Cataracts delivery defects maximum cancers Many different extreme ailments

Answer 4

I forget specifically what material, but there is a vertain material which does not let radio waves pass through. When you're inside it, your cell phone would not work. Try putting your cell in the microwave and closing the door (but don;t turn it on!) and I guarantee you will have no signal.

If you try to open the door, as I'm sure you have done at least once while microwaving something, it stops. That;s just a backup incase you're an idiot

Answer 5

The holes in the screen of the microwave oven are smaller than microwaves. They can't pass through since the microwaves are larger than the holes in the screen.

Answer 6

Door interlock and metal screening behind the viewing glass (leaded glass on the more expensive models). The rest of the unit is double skinned metal with an air gap.

Answer 7

All these answers have varying levels of correctness- I just wanted to add that when I was a kid, my dad worked in Heating and Air Conditioning and Refrigeration, and we were in a back kitchen of a restaurant one day, and saw another service guy there putting on this big lead shield that covered his chest and groin area- curious, we asked him what he was doing-He said-
"the company requires us to wear these when we work on microwaves..."

Answer 8

it has an earthed mesh and case to cut down rays to the recommended level as long as you aren't sitting near it like some people do in offices

Answer 9

A metal mesh seal and, if you notice the door glass, there is a metallic net.

Answer 10

The whole box is screened by metallic mesh.
