Magnetrons require a microwave oven/resonance chamber to build up enough heat by the wave going over the same area again and again. I've tried (not to burn anyone's house down though)

Cool to experiment, BUT A geiger counter doesn't detect X-Rays!! Totally different frequency. There is a reason why radiographers use fluorescing screens.. because they DO detect x-rays -- big time!! Yes I was an x-ray engineer. FFS get yourself some eye protection as you are probably already well on the way to cataracts.. And by the way you need 100K to 150KV, 200K is too much, the x-rays will just pass through everything. Medical x-ray tubes use an aluminium sheet to protect you from the low 50KV stuff which is seriously damaging to eyes and skin. :-)
Yup the job of a geiger counter is to detect radiation. Although, x-rays are radiation, the amount of radiation produced by x-ray CRT is not a significant amount to cause cancer. But can cause cancer in the long run. But its very true that the geiger counter cannot detect x rays. if that large tube produced x rays, the geiger counter would have started beeping WHILE the high voltage was on. NOT after.
Ryan Haquim the reason there is a delay between the tube being on and the Geiger counter reading is due to the slow response of this particular Geiger counter.
Geiger counters do detect X-rays because they are ionising and you can check this on google yourself. Inside the counter the geiger-muller tube contains a gas is ionised by the radiation and this produces an electric current. The main reason why fluorescing screens are used is because you can generate an image from them. The large tube probably did produce X-rays, but the counter was positioned too far from the tube to detect much of it. A lot of the newer tubes are impregnated with lead so this could also be reason.

+fo shizzle Is not that much. You can have 10 amps at 250 volts in main and get 12000 volts at 0.2 amps.... It will be 2.5 kw/h. 5 Kw is 1 euro in Romania. My last electricity bill (for 2 months) was 200 Kw - 50 euro. So you can play 2 hours non-stop with a step up transformer as said and pay 1 euro....
i spent a day in Chernobyl and pripyat in 2008. the geiger counter read 5000 (normal background .5-10) and i wasnt worried. being in a room with them wouldnt worry me either. long term exposure is what you need to worry about if i remember correctly...
I suspect you're correct. I am not familiar with this particular Gm counter and whether it can differentiate between beta particles and X-rays. 200 kV isn't really high enough for X-rays.
This may seem a bit late, but for anyone who is watching this in the future, in AUSTRALIA the legal dose for an un-licenced person is 25.0uSv/h with an allowance for up to 1mSv per year. And yes I am a licenced Industrial Radiography Technician, I'm not just spitting numbers out the top of my head.
I wonder how high it would've read had it been for a whole minute? I have the same Geiger counter and it displays the average of the last minute, meaning the intensity of the x-rays were actually much higher than what the reading was....then again, the reading is in uSv/h, so a minute is only a 60th of that.
9.70 u/sv might seem high but that's about how high the radiation is when you fly in an airplane at cruising altitude. It's really not dangerous at all even over long periods.
Getting there. Electrons can't move at c (they have mass, which would cause all sorts of physics to break), but electric fields can. This is arguably the most counterintuitive thing in basic physics, but while electrons can't move at c, electric fields can. The best way to think of this is as if the electrons can see each other. When one electron sees the other start moving, then the observing electron starts moving. (contd)

Ok... here is a question for you. In my youth... about 1975 or so... we took a color picture tube and placed it on a metal plate (ground plane), then connected the output of a 15,000v 60mA neon transformer to the side port... with a chain suspended from insulators about 3 inches (7.6cm) above the tube, and connected to the other side of the neon transformer. (Basically a Leyden jar from hell) We fed it with 120vac run through diodes to produce pulsed DC. It would charge up a bit, then make lightning. Just how stupid were we on that? Didn't think about X-Rays... I was 15 at the time.
While I would agree with most of the comments on here about how this is likely a malfunction in the Geiger, it's worth taking into account that the Geiger was measuring steady higher readings of X-rays which each coincided with an increase in voltage to each tesla coil on each attempt. Malfunctions, or spontaneous readings in the Geiger due to large emf would show up as jumps or spikes and would likely have inconclusive readings rather then the steady output variables which can be seen. The only way to rule out that emf was indeed causing the reading would be to measure its strength and place the meter further away. But really though, chances are X-rays were indeed produced. Be safe out there ! Leaving the room did little to help you btw... Unless your walls are thick concrete or some sort of reflective metal. Given the reading on the Geiger was relatively low and the period you were exposed wasn't that long you should be okay... But perhaps a insulated faraday cage around your next test, set it up to encase your tesla coils, put the Geiger inside with your camera in a non reflective insulator so you can avoid further harming your cells in future experiments.
That was wild I have to admit bringing these old things back to life... Watching the electronic arc. Another you for a great Holloween display.. with the arc jumping was really interesting ...
One thing to be aware of is the radiation pattern from overdriving vacuum tubes (like you are) can be extremely uneven. As such, you may get artificially low readings because the geiger counter is not in a hot-spot of the beam. There are some cool photos around the internet of people measuring the emission patters of various vacuum tubes with phosphorescent screen, and long exposure photography.
If X rays were generated for real, camera would go crazy and crash. Also efficiency is only about 1% so you have to put quite a lot of power to get something visible.
Pretty sure you need to power the tube heater / cathode before you'll get any serious x-ray emission. It's streams of highly accelerated electrons striking the tube structures that produce the x-rays. With a cold cathode, the electron supply is limited to free electrons in the cathode materials. Fire up the heater and I suspect things will look very different.
at 5:03 is about what you would expect from a typical CT scan. X rays only travel in a straight line though, so the readings would possibly be lower in other parts of the room.
You should get a pressurized integrating ion chamber it will detected the lower energy xrays and the pulses as well. So that geiger counter would undercount exposures.
Instead of buying a geiger counter you can also download a dosimeter app for your smartphone which uses the camera chip as a radiation detector. These counters are even able to detect pulsating radiation which other electronic dosimeters can't. Even the expensive ones. A lot of new and upcoming electronic personal dosimeters will be based on this technology.
100 µSv/h It is necessary to take protective measures, e.g. to shelter indoors 30 µSv/h The dose rate measured at a distance of one metre of a patient that has undergone isotope treatment. When the dose rate is less than 30 µSv/h, the patient can be discharged. 10 µSv/h Some protective measures are needed, e.g. avoiding being outdoors unnecessarily.
Since the electrons can't see each other faster than the speed of light, the movement propagates at the speed of light. This is how electric fields can propagate at c even though electrons can't move that fast. Electrons simply cannot reach the speed of light, since they have finite mass, and particles with mass can't reach c, so you can actually have a stationary electron (though it's really, really hard). Essentially, voltage sets the speed of the electrons. The more voltage, the (contd.)
X-rays are created when an accelerated electron slams into a solid target at an extreme velocity. The very high voltage accelerates the electrons across the empty vacuum before slamming into a solid object. This is called "Bremsstrahlung".
Puts himself in harms way for our entertainment, yet still considerate enough to warn us about potential ear rape. If you ever come across the pond, the cider is on me.
Maybe you can get xrays if you use heavy metal with high fusion point as anode and cathode, such as tungsten, iridium or molibdenium, and voltages around 100kV. That's what is used in xray tubes. A typical chest xray uses 120kV and 20mA.
And the problem with the Geiger Mueller tube is it doesn’t really detect x-ray and Gammas that well. for that you need a scintillation detector. Like a Radiacode 101/102
There is no X ray in this video, the uses tube is a GU81M, they have a normal anode voltage of up to 3kV and flash over in cold state at about 15kV (sadly my own experience) Thats not enough to crate X rays that can peetrate the glass. The reason for the counter to show something is, that its pretty close to the transformer and tube. They generate lots of EMV when the spark developes inside the tube, thats enough for a non shielded geiger to crap itself.
NIOC630 counters are very sensitive to induced current, being precision high voltage devices. You'll burn/fault it out before you could trigger a false event. 3-15kv is also more than enough to create X-ray photons that will pass through glass.
You should put a Geiger Counter in front of the Cathode Ray Tube telly you cranked way up that was giving off that really weird horror movie demonic possession green glow.
I put voltage into a vacuum tube and store unlimited amps in a silver wire. The voltage came from a cylindrical hallbeck magnet aerodynamic journal bearing.
That's such a tiny amount of radiation though. Wouldn't do it without a geiger counter, but still. You'd have to be in that room for almost a full 24 hours to receive a dose equivalent to a mammogram.
You may want to invest in a good lead apron or suit or something. Maybe make a safe room with a good thick layer of lead paint (or just lead). Be mindful of building codes though, and remember that lead is pretty darn dangerous all on its own, which if why I wouldn't normally recommend that someone using lead paint. Actually, just forget about using lead paint altogether, because it's more trouble than it's worth.
Remember that meter is measuring microsieverts/hour, so a reading of 60uSv/hr for one minute (shorter than he ran it at, by my count) would yield about 1uSv, or about the same radiation dose as eating 10 bananas.
