 Please don't tell me he's about to do what I think he's gonna do. I'm not sure I want to watch this part There's just scatter radiation all over the place as soon as he starts this up I don't know what they're doing. Welcome back to my channel everybody for those of you who are new around here My name is Michael aka Dr. Chlini I'm a radiologist doing my final year of training in interventional radiology in New York City on today's video We were going to be discussing a video that was recently sent to me of a couple of friends who decided to make their own Homemade x-ray gun. You heard that right. We're gonna watch this video and get a radiologist perspective on the whole thing So let's go Now just looking at the start of this video it Just looks funny to me. I don't know what's happening here, but we'll see we'll see In this video, we're gonna show you the real power of the x-ray gun that we have assembled. Let's go guys Awesome move them this time. We are well prepared We have a lead set of armor So if that is in fact made of lead, I'm pretty impressed with their ingenuity they are covering all the vital parts including the Gendals and also the trunk which is good and they also have a little hat on the head which I don't really know what that is There's a super modern multiplier in oil. I had to find this one It's an ancient transformer from a lamp TV imagine that I don't know what he's talking about I don't know. I think the photo multiplier tubes is the way of multiplying power. I'm not too sure on the Electrical engineering aspect of this whole thing safety is everything. We are insulating the third multiplier Now we see that this wire is not insulated Well here from this side and that side I'm actually pretty impressed so far because it looks like he has some sort of training in Electrical engineering or something. He knows more than I would trying to put this together now I can turn it on and enjoy the rays of good You don't need a song He's telling the x-rays the rays of good They're a little too lackadaisical about building an x-ray gun here. It's kind of worrying me So we'll see where this goes and you to high voltage the electrons in these tube are starting moving at crazy speed And they're hitting the anode There it is. So that's how the data rays of good come from it So basically he's saying he's describing an x-ray tube He has this huge power bank that goes through this photo multiplier tube It heats up the cathode which is where all the electrons kind of come off of but it gets so hot it emits Electrons off of the cathode electrons hit the anode which is made of usually tungsten X-rays are admitted and go into a certain direction Usually points it downwards towards the patient. That's how x-rays are developed. Let's get down to experiments Wearing this armor. I feel completely safe I'll say is where he's wearing armor Homemade armor around his chest and he feels completely safe standing 10 centimeters from this homemade extra machine That has no housing on it, which means there's nothing capturing the x-rays Which means there's just scatter radiation all over the place as soon as he starts this up I'm afraid to be electrocuted Why nothing happened? Please don't when you try this at home. I have to start by saying that So I guess they were successful in this extra machine the first time they turned it on however Again, like I said, he has just scatter radiation going throughout the entire room Affecting the cameraman whoever else is in there and especially him who's standing right next to the x-ray tube Also x-rays are usually taken in milliseconds. They're not just Held in the on position like a flora machine would be so you're just constantly admitting radiation that whole like 10 seconds He was doing that was a feeling I thought thousands of needles were kind of touching my body slightly like So that's already worrying me that he's getting like depends a needle feeling when he Has that extra machine on and he's standing like a couple feet away from it Now we're going to carry out one of the most dangerous experiments. I Love how this is the dangerous experiment not everything we've seen so far He has no radiation goggles, but I guess his chest head Well part of the top of his head is covered, but his eyes are not covered his chest and his genitals are covered so I guess Sort of okay. All three perform by professionals. That was the sake of science Please don't tell me he's about to do what I think he's gonna do. I'm not sure I want to watch this part I thought the small charges tingling and when I turn it off the current got on me. That's normal So they're experiencing some sort of interference here causing static electricity or Electricity elsewhere coming off of this machine that they made and affecting them while trying to take a homemade x-ray of their hand working So at this point he has no protection on him and his actual his genitals are at the same level of the x-ray machine, which Clearly he does not care about I knew that the stupidity in this video is Next level the most dangerous thing now try it terrified Imagine making a homemade x-ray machine and then testing it out on your own hand First the simplest second is modern and the third is the best it can measure up to 100 rangans the most powerful radiation Keep in mind here He's measuring just radiation in the atmosphere surrounding this machine, which is everything I'm talking about There's a ton of scatter radiation being produced by this x-ray because normal x-rays are produced in a housing that Basically streamline the x-rays down in one direction and they're not just going all over the room. Let's go So what they're doing here is basically measuring the distance from the x-ray machine to see the radiation difference And this should follow the inverse square law and for those of you don't know the inverse square law It's something we use every single day practicing radiology It describes the dose reduction as the distance from the x-ray actually increases So if we increase our distance from the x-ray source by a factor of two Our dose is reduced by a factor of four whenever we're doing a higher radiation Angiogram or digital subtraction angiogram. I usually take two steps backwards, which means my Radiation is likely decreased by a factor of four with each big step Comparatively if you were right near the x-ray source like this guy has been the whole time He experiences the entire Radiation dose almost I'm curious to see how much radiation they're producing here. It was nine Million micro-rankers per hour. What this one showed it. It was all scale nine million joking ten times more than death bucket So nine Rankins an hour at three meters is pretty alarming. We usually use millisieverts as radiation Unit in radiology. So basically nine Rankin an hour is the equivalent of 90 millisieverts an hour or essentially like nine CT chests per hour So that's quite a big amount of radiation I'm trying to remember in the Chernobyl episode what they said how many Rankins an hour Chernobyl reactor core is producing around that area. I remember being something insane either way This is a lot of radiation to be just standing next to while you're turning this machine on and off And we're going to go even further. I couldn't imagine it will be reaching this far. I Mean think about his neighbors who are just I don't know if he has any neighbors it looks pretty you know Solo out there in this one house, but if there are neighbors, they may be experiencing some of this radiation too Which makes this experiment wildly unsafe, but we knew that already. Don't worry. We have no neighbors They have no neighbors. Don't worry. So no one will be hurt. Yeah, nobody will be hurt But them and keep in mind here. They're not going to experience any of the effects of this radiation in the short term probably They'll probably experience some Static effects or increase their percentage of getting cancer and later on down the road being exposed to this kind of radiation And I don't know how many times they've run experiments like this. Hopefully this is the last time they ever do this Comment below if you think this shield is going to help them or block any radiation I'm surprised if it actually is lead. It'll help if it's not, which I don't think it will be but we'll see Anyway, all sounds of my current hands lean. It lets the radiation through. Oh my gosh, but how so the protection worked somewhat But the lead won't block all x-rays, especially an intense beam coming at them unregulated All of you are here to see my toes in the x-ray band. That is going to be risky Why do they have to do this? Why? Why? Awesome. Now we can move them That's enough This is basically just unregulated fluoro. This is essentially my IR procedures I do unregulated at home with the beam just going everywhere and scattering everywhere Holy moly. Why does he have to use his hand? They already did the foot. Why do I have to do more? Let's check the shooting distance of this gun Let's prepare the special stick. So I think now they're outside gonna try out this x-ray gun in the outdoors and see What it does. I don't know what they're doing, but at least they have a stick to turn on and off now I think they got sick of being electrocuted Turn at all. He's keeping it working. Oh my gosh. Sasha is a slowpoke today Instead of shooting he already does all the time This is so bad. So even outside this is registering at many meters away from it So there's nothing kind of for scatter radiation to kind of go off the sides and scatter around and cause a False or misreading of this device, but he's still getting a ton of radiation Outside this far away. The x-ray machine is just crazy. It's it's funny to me. Well, it's not funny But not only are they getting so much radiation, but they're also getting electrocuted by it as well Basically, this is just natural selection at its finest in one video again I'm worried about the long-term effects of this kind of radiation they're experiencing But we'll never know unless we follow these guys for years This is some crazy power they're producing recently the world is assembled a huge demographics counter in a university So he got this extra tube from an actual x-ray machine in a medical facility And now he's actually going to play with a real x-ray to but at least this one has that housing around it Which is what I'm talking about so there's actually just one window where the x-rays fly through so they can actually hear it in a linear fashion towards the patient rather than They're just going everywhere out the room now obviously some x-rays do escape this housing But it drastically limits the number of x-rays use this powerful x-ray to kill birds in the skies You're going to see it in the next video These people need another hobby that isn't this my skin is burning and it's reaching like crazy Can you measure the temperature? He may have gotten some actual Deterministic effects from this extra machine which are immediate effects, which is what we worry about in our business So sometimes our long procedures that take you know hours and hours and we produce a lot of radiation Focused to one spot of the skin it can cause some skin burning Almost like a tardy like a square sunburn on the skin from the x-ray of tube or it can also cause Epilation or hair loss as well among other things which hopefully this guy doesn't have any of those all right So what do we learn today? Let's see don't play with x-rays because they are not safe You can get burned by them in multiple ways There's a lot of meanings behind that but anyways, hope you enjoyed this video There's a little educational on with this crazy X-ray building a homemade x-ray tube if you have any questions leave them in the comments below if you like this kind of video I'll do more of them. Otherwise as always follow me on Instagram and TikTok and I'll see you all on the next video
