What makes a Magnetron dangerous
Вставка
- Опубліковано 7 вер 2024
- The real hazard is the beryllium oxide that is contained in the ceramic insulators. They are no hazard as long as it's not disturbed and does not become airborne. Often people are taking them apart for scrap or to get the magnets and may not know that any breaking grinding or cutting may free the beryllium and cause an incurable respiratory health problem called chronic beryllium disease.
Believe it or not, magnetrons for common microwave ovens made since about 1980 have aluminum oxide insulators rather than beryllium oxide. The old amanna radarrange ones do have heryllium oxide. Since the 1990s they use pink ruby alumina to make them easier to sort when recycled. 🤓
Those symptoms you list sound just like the symptoms of getting older.
That's what I thought...no cure for that either
Horsetail is an herbal supplement that removes heavy metals from the body. Taken in large doses it has been known to remove the mercury fillings in teeth.
Since Beryllium is a metal, horsetail can be used to remove it.
@@SolutionsNotPrayers there is a large difference between Mercury and Beryllium, just looking at the periodic table.
@@SolutionsNotPrayers Beryllium is NOT a Heavy Metal, it’s actually a light metal like Lithium or Aluminium
DANGER ⚠ Before attempting to remove a magnetron , Be absolutely sure to discharge the capacitor and the magnetron itself because no matter how long the unit has been unplugged , They can hold a charge that is LETHAL , And NEVER NEVER ATTEMPT TO POWER UP A MAGNETRON WITHOUT IT BEING INSTALLED IN THE MICROWAVE , Doing so will expose you to very dangerous levels of microwave radiation , If servicing a microwave yourself , It is strongly advisable to get a microwave leak detector to make sure there is no leakage of microwave radiation , In everything you do , ALWAYS PUT SAFETY FIRST!!!!!
ironmarty Sharpe have you seen the video by those silly russions on Kreosan channel? Door open holding shit in front of it.
m3sca1 That sounds tragically hillarious.
InsideOfMyOwnMind they do all sorts of dumb things for views
I just +d both of you because if you combine your opinions into one person that is me.
put your cell phone in a microwave oven and then call it.. any leaks? how about 5G? danger will robinson!
Yes, public spirited to warn of the possible dangers of Beryllium oxide dust and what it can inflict upon the unwary. I note others have clarified the colouration of ceramic containing b-oxide and that most now use aluminium oxide instead. However, the magnets may be fun for us eternal Peter Pans, but the ion chamber is fashioned entirely from copper, therefore does have some value to scrappers
Magnetron operates on about 2000 volts DC, which is derived from one transformer winding with a simple diode and capacitor. About 6 volts from separate transformer winding are used to heat the filament. Filament is mounted in the center of a circular chamber in the metal block with a high vacuum, with several small. straight channels leading radially outward into small chambers. Electrons emitted by the filament travel into the smaller chambers, where external magnets force the electrons to spin, emitting microwaves. These microwaves exit the end of the tube and are guided to the oven.
More like 4000V DC, the 2000V you mention is AC straight from the transformer before it gets half-wave converted to DC by the diode and doubled with the capacitor.
Filament takes 2 or 3 V not 6
I believe that "sensor" that you pointed out is actually a "thermal cutout", basically, if the device gets too hot, that trips, killing power to the magnetron.
defined : thermostat.
Jeremy Allen “
Thermal cutout or thermal switch is actually the correct term. A thermostat is used to regulate temperature. It wouldn't be used to shut something down in an emergency.
a thermostat will switch back on relatively quickly after having cooled beneath a certain temperature.
a thermal cutoff might trip back after a while but usually they either have to be manually reset or they are one shot switches that need to be replaced.
Split hairs.
Yikes! Don't forget the radioactive Thorium electrode in the vacuum tube!
The what?
@@qrelectronicrepair1802 Vacuum tube... vacuum chamber... same principle. Thorium is an alpha particle emitter. It used to be used in certain kinds of welding rods, and in the filaments of antique gas lamps. Alpha particle emissions can be blocked completely with a piece of paper. You don't want to inhale it though, so unless you are cracking open the vacuum chamber to the magnetron, and grinding on the tiny electrode filament you have nothing to worry about.
Dude, I weld with tungsten/thorium electrodes, guess what we grind them to a point... frequently!
Vacuum tubes have throated filaments as well....I guess a magnetron, is a vacuum tube of sorts?!?
Oh, geez...that's nice to know. When I was a teenager working at Sears product services, I used to tear mags apart to get the magnets. I'm not really sure if I chipped the ceramic, but it would not surprise me. Smh
You'd know if you did.
jeez how tf are you not dead old microwaves didnt have the part that bleeds the charge of the capacitor so they would prob still have most there charge from testing if you fucked with it or even some models touched it you would instantly die
@@elliott8596 That is not for sure no. Many will never get any side effects.
A magnatron operates at 2.450ghz (2,450mhz) that device attached to the side is a thermostat that opens when the temperature goes above a preset level. If you pop the metal cover off the bottom you will find 2 coils (Rf chokes)
Thank you Sir for the caution alert about the danger of a Magnetron.
I pulled apart a bunch of these in my younger days and I've still still got the magnets, don't have those symptoms but since finding out about beryllium I certainly won't be doing it again!
Magnetron is a vacuum tube diode operated with a positive antenna that issues its output into the cooking chamber.
I have heard that most of the time if the ceramic insulator is white, it is most likely beryllium oxide. However if it is a pinkish colour, then it's most likely aluminum oxide. That could be not entirely true though, still take proper precautions just in case it is beryllium oxide.
Thanks for explaining with so much detail. I want to disassemble an oven and was freaking out. Only knew the capacitor and the magnetron were the two most dangerous parts. I feel better informed and prepared now..
Yeah better not touch both of those things, both are potentially deadly xd one of those things you don't want to service yourself ever if you can avoid it.
Thanks for pointing out all the safety points, good for everyone.
What about not powering one up without proper shielding? That's safety concern number 1....
Thought I'd seen somewhere that they stopped using that radioactive element in these things. There was a way to distinguish looking at the magnetron to be able to tell the radioactive ones from non radioactive. Though I'm not 100% positive on this. Just seems I remember seeing something about it.
Beryllium isn’t radioactive. It’s toxic.
Exposure Limits for Beryllium Oxide
NIOSH REL
Ca C 0.0005 mg/m3 See Appendix A
OSHA PEL
TWA 0.002 mg/m3
C 0.005 mg/m3 (30 minutes), with a maximum peak of 0.025 mg/m3
I hit one of those with a hammer as a kid years ago, I can only hope it used aluminum oxide...
Philip Blumel same here 😂😂
are you still alive
Huh! All those symptoms describe me just getting old.
Surprised he didn't also say balding, love handles, and the requirement of bifocals.
Ha! Well, I still have being young at heart, I suppose!
Element of Kindness exactly. I've been 18 for 44 years.
typical brony
And no cure...... figures
gotta love feeling young even if your not
Some people get very sick of the microwaves: there is tension in the muscles and gives fybromyalgi and chronic fatigue. Most people have no negative results.
They don't use berillium any more. Not for the last 30 years. Aluminum oxide. Perfectly safe these days.
Bodragon uh huh, you've seen them being made? Are you even sure where they're made?
You are incorrect. While it may not be as widely used as it used to be, it is still in use. It has unique and valuable thermal properties. Mitigation of it's hyperallergenic affects is not difficult.
Wow! Thank you for the public safety message!!!! I don't know what a magnetron even is, but i will be on the lookout if I ever am in doubt. And I'm being serious, in case it seems like I'm being sarcastic.
is the microwave generator in a microwave oven
U.S Active denial system: "Hold my beer"
For one thing, you point it right at your eye, and in about ten seconds you have heated the lens of your eye enough to develop cataracts.
Thanks! You prevented my future stupid self👍🏼👍🏼👍🏼👍🏼👍🏼. I was looking into pulling the power supply from a salvaged microwave to make an emergency welder
ManyThanks for sharing this very important safety information!
The aluminum vanes remove the heat, there is copper inside, and steel. All of it can be recycled, the magnets can be repurposed. The ceramic can be trashed. So don't throw it away.
I've read that Beryllium oxide was only used on old magnetrons, "newer" magnetrons are supposed to have Aluminium oxide.
I've been trying to find more info on that though.
+Gordon Freeman i think so too, becuse beryllium is expensive
The one in this video isn't beryllium. If it's white then it's aluminum oxide. Pink ones are beryllium oxide
JustinLodes
Are you sure?, because I've read different things all over the internet.
If you could point me to a good source, I would appreciate so much.
Your right. Pink color is addition of chromium dioxide for extra hardness.
Look up manufacturers data and find Samsung and panasonic for example have never used BeO.
BeO is 500 more expensive than Al2O3 (Alumina) which does same job for domestic apps.
BeO is used in rocket engines, radar systems or industrial microwaves above 50Kwatts.
Wikapaedia is of course full of mis-information about these cheap domestic ovens
Why use a poison in a domestic product which has a fan to vent its inside to the outside ( breathable air )
So the question remains, is aluminum oxide harmful?
Thank you sir, most appreciable caution and information.
If i broke the beryllium tube and left the room immediately without breathing can i return the next day?
Wow. Of all the things I've taken apart, messed with and or just plain destroyed as a kid, I am so glad I never screwed with a microwave. I'm certain I would have taken the ceramic out just to experiment not knowing the dangers.
I’m a kid and and I just posted a video taking apart a microwave but I have a great understanding of the dangers
I used to rip stuff apart for fun, years ago i was probably 12-13 or so disassembled a microwave. Not knowing the potential dangers like i do now. Took the magnets out of the magnatron (which are still hanging on the work bench) and somehow didnt get shocked by the capacitor. Man i got lucky.
when i was young i loved destroying shit like that for fun. i did a microwave once, which is still lying around, and somehow didnt chip the ceramic and somehow didnt get 2000 volts sent into my body.
Damn! I thought he was going to show us how to make a Ray Gun out of one. ;-)
Thanks for the "beryllium" tip (no pun intended).. I did not know that :)
thank you for saving me...I was going to get the magnet out!
It's alright if you get the magnet out. I've done it a few times. You just have to be careful of the ceramic. Practice safety even if it doesn't contain beryllium.
I'm no electrician engineer, but when a microwave is in use how does the berilyum oxcide not contaminate the food? What safe guard is in place?
Thank you for the information. Be safe folks.
Damn it ! >:o(
Thanks for spoiling my fun , I've got 2 broken microwave ovens at home and I was gonna pull them to pieces to get the big ass magnets out of them.
Now, I'm not gonna touch it.
Get a respirator, some safety glasses/goggles, and a decent pair of gloves.
And jus be careful it's easy to get the mags out w. Out breaking those things
Why bother you can get much stronger magnets off of eBay for cheap
i have major joint pains and have breathing problems , i have been exposed to ceramic dust and yet the doctors have never checked if this is the actual cause of my issues . the way i see it is that everything is about money .
White ceramic seems to be just aluminum oxide. Although I'm not sure enough to recommend anyone breaking it anyway. But if it appears pink that is most probably beryllium ceramic
Thanks for the warning. I have an old microwave that I wanted to remove the magnets from now I think I will just toss it.
The electrons don't bounce around they are bent at 90 degree angles and spiral around. The Magnetron Vacuum tube has copper fins inside that portrude from the chamber wall. Each time an electron passes near a copper fin it generates voltage in that region. When this happens enough an RF signal is generated and then coupled to the output on the tube via an internal antenna. That output is also the copper nipple that is cold welded to seal the vacuum tube. There is no thermal cut out on the tube. Those are mounted on the magnetron and the cooking cavity! LOL!
During ww2,as a firecontrolman on DD540, on Oahu,we were sent to A hill above salt lake,where they had a primitive radar station. It was here that we first got to operate radar. Then, before supper we walked down and went skinny dipping in salt lake?Anyone here familiar with that?. Hickham was the base.
Cooking frozen cheeseburgers in your microwave will kill your appetite.
Suppose the newer ones are beryllium free, how does one tell the difference? I feel like looking online will only give me very mixed and confusing results (what a surprise), so better to treat them all the same and just assume they have it.
That's good to be safe than sorry. But to answer your question. The white ones are aluminum oxide. If it has pink ceramic then is beryllium oxide
You are repeating misinformation
There's no way to tell, at least not at home. Considering where these things are made, it really is best to assume the worst
Question: what type of facial protection can be used to protect you from beryllium?
the dangerous element of beryllium is breathing the dust, (caused by breaking or agitating it) beryllium is highly compatible with oxygen meaning the molecules quickly attach, then you breath it, and it attaches to your lungs. it can kill you depending on how much you breathe. it is suggested to wrap the beryllium part shown with tape.
Why don’t those things have warnings all over them. Some of us who are curious and tear things apart to see how they work are at great risk.
I'VE GOT ALL THOSE SYMPTOMS BUT NEVER BEEN NEAR A MICROWAVE
Because your phone is one big microwave the network towers as well. Even if it states it's non ionising radiation you're still getting those waves
@@Alpaax true mate
My understanding is the white insulators use Alumina, the pink or purple ones contain Beryllia.
Magnetron is dangerous because he is the enemy of the peaceful Autobots.
I'm guessing that beryllium stuff you speak of wouldn't be a good cut for the product I'm dealing on the east side.
i mean, it is a valuable material so maybe you could get some money.
next on youtube: "DIY How To Disassemble A Magnetron"
Given the wavelength of 2.45 GHz microwaves generated in a typical magnetron, why is the antenna so stumpy? How does the antenna actually radiate?
So that was worth watching.

So don't crack the ceramic. Thanks, glad I look chit up anymore before I take things apart. I've taken everything from televisions to vacuum cleaners apart. Nothing dangerous in a vacuum but a tube tv is full of led if you crack the tube throw it away or try to recycle it somewhere.
Thanks for the heads up. Now I wont mess with one
I learn something here. Thanks.
Thx. Never gonna touch that thing.
Yeah was gonna take an old microwave apart that's door sensors went to get the magnatron---- very glad I bumped into your video because that's not a well known reason why magnatrons are dangerous, most people think its just the microwave energy that's dangerous
Where to dispose this magnatron pull out from dead oven?
Post apocalypse games/films should have a dude with a huge pile of microwave ovens with their cavity magnetrons removed and used for radar equipment
I do not know if the magnetron sizes are standardized, but this one looks EXACTLY (same dimensions, but the insulator tube is pink on mine, not white), like the one in the microwave oven I did disassemble. It was made (magnetron) by Panasonic, model 2M167b-M73. I do not remember the brand of the microwave oven, it wasn't Panasonic tho. Some German or Swiss low cost brand.
Also I doubt it has any Beryllium Oxide in the insulator thingy. I am sure it would be marked at such. I am searching myself to figure out if mine has any Beryllium without access to XRF or MS equipment. I did find some dubious claims about color (white vs pink) being indicator of anything, but I do find it not consistent, and not anything useful. Both Beryllium Oxide and Aluminium Oxide do have additives like chromium (for various reasons), and others than might change its color. Considering beryllium oxide is simply more expensive (but indeed better in thermal properties) than aluminium oxide I doubt it used for magnetrons these days, especially ones coming from Asia. One quick check is to check the weight and volume (i.e. submerging in water) and compute density.
As of the Beryllium in any form (metallic Beryllium or Beryllium Oxide), especially as a dust, the exposure is not a joke. Even single dust exposure can lead to serious health issues.
The magnatron was aquired during an exchange of technologies with aliens, some of the things we traded included toothpaste and washing powder!!
As well as smoking, booze and gambling!
Yes aliens are total addicts! No, I'm serious, totally!
flat water proves the 'globe' is a lie and the bible is true! the only thing that was ever lauched into space was our imagination! Psalm 104:5 He set the earth on its foundations, never to be moved. God Bless! billions stolen yearly from the sheeple!
Can anyone tell me if it is safe to cut apart a magnetron without damaging the ceramic to get the copper cavity for the copper?
BG Tech you can find a good and helpful demonstration in youtube channel: Tin Man Scrapper.
as a radio engineer, you can repair one but you need special tools
All airborne metals are potentially hazardous, including silicon ,calcium, sulphur,carbon,etc. What comes out of your tailpipes is extremely hazardous ,killing countless numbers this year .
I don't think carbon is a metal, but lungs don't breathe solids.
Wear a dustmask and. Put the magnetron in a clear plastic bag.
WTF, if this is true for all Microwaves, why the fac, none of them say, "if breaks leave room, call 911"?
If anybody is smart enough to tear it apart and break the emitter antenna then they should call nine-one-one on themselves really.
Good info to know.
You need to be very careful not to let optimus prime anywhere near the magnetron or it will fuck your microwave up.
I gothe magnets. How do we properly dispose the magnetron?
I remove the magnets and put them around the oil filter on my car.
I mean you could chip the ceramic away, you just have to be smart about it, like doing the dangerous part in a bucket of mineral oil to catch the harmful particulates. I personally wouldn't chance it though.
Thank you. A life saver
just be careful don't go hitting them with hammers or throwing them on the ground making them dust up
The other hazard being turning it on?
Yeah, I thought the dangerous part was possibly frying your brain with microwaves.
Capacitor..
In other words: Magnetron. Do not eat. Do not inhale.
Old tool makers would get this from working with beryllium for years and years. Dont think 1 time would hurt you
That magnetron doesn't have beryllium oxide. It has aluminum oxide. Pink = beryllium and white = aluminum oxide
Pink is addition of Chromium dioxide for extra hardness and is used here as a leftover product.
BeO and Al2o3 ARE BOTH white
John J. Rambo right Al2O3 white , Be metal is toxic and fatal in small quantities.
Yes, beryllium is white. Its used on rf tubes and xray tubes also.
I have tons of magnetrons both pink and white ceramic.. are they both as dangerous?
I wish i would have known this. I don't recall breaking the ceramic but i have harvested hundreds of magnets from them. I work in a appliance repair shop and I cant count how many i have dismantled... damn. Very often I suffer from shortness of breath and aches and pains, this worries me. 🤔
How are you doing now James? I’m here because I just removed the cover on a microwave to replace the bulb, now I’m freaking out! Guess I’ll come to no harm however as I didn’t even touch the magnetron. 😥
Damn...Makes me wonder while being a kid. All the crap I took apart...Just because. Did I expose myself to beryllium?
I remember breaking alot of these stuff when i was a kid special the little white thing on it
God dammit, I knew about the damn beryllium I was hoping you were gonna talk about the dangers of it when it's ON
wow, thank you, Im looking into scrapping stuff and this is definately good to know
hello. thank you for the video. is it safe to replace the antenna cap, if the insulator is made of beryllium? will twisting the cap off break off any of the ceramic or disturb it?
If it's white it dosen't contain berylium just in the cathode it has tholium or something like that it's still radioactive and dangerous .
How do I safely take it apart I'm trying to get the thorium
They technically are an antenna and they emit radio waves
Hello. Could you wrap a piece of tape of some type around the beryllium before disassembling the unit and just leave it on the unit afterwards.
I scrap em. .Magnetics..Copper...and Aluminium...
I completely shattered a microwave as i was younger, am i going to die?
Maybe
Of course you're going to die. May take 50-70 years, but everyone dies. Sheesh.
Andrea Maccanti If you haven't already, you should soon start acquiring random superpowers.
i believe Beryllium banned many years ago due to high toxicity, its not possible at this time they using it at kitchen device also if it does they put some warning sign on it for sure
Andrea Maccanti * Yes, nobody gets off this rock alive.
Hi could you tell me what gold/brass looking metal the woven mesh gasket is in the top of the magnetron
People are putting these in their vehicles with a magnetron in the front and back of their vehicles.
I've scrapped them bad boys An salvaged the magnets many times those things chip they don't explode dust like in a berillium factory that make ceramics . So how many of these has this guy actually witnessed passing dust into the vicinity of the scrapper or dismantled in person
What happens if you take the back Off
I broke one out i had no idea ..since i have been feeling dizzy and nauseous ..guess i'm fucked...shit..now what the hell do i do...ty for this wish i had known before..
fretzopenmic was the tip pink?
Btw its not Beryllium but is The Beryllium oxide
i think, jusing Asbestos Cement would be safer!
Do they still use this in microwaves?
You could build a giant one and make a death ray.
