| Homemade X-Ray Machine: Liftoff |

My phosphor screen is 3m trimax 12, which (I believe) produces sharp images at the cost of dim image. Perhaps this would work better? The only downside is that is is quite expensive from Russia. https://m.ebay.com/sch/i.html?_odkw=x+ray+intensification+screen&_from=R40&_trksid=m4084.l1313&_nkw=x+ray+intensifier |

Modern X-ray machines can take more images than that. When I'm at the dentist they take at least four images in a minute, and that's with a 90s machine. But still only pulses, at some sort of high frequency. https://hackaday.io/project/3665/logs |

It all comes down to anode heat capacity. You can run a tube for much longer periods at low current but if you crank up the kVp or mA then the exposure has to be shorter to avoid overheating the tube. There is also a heat capacity of the whole head, they are filled with either oil or in some cases SF6 which absorbs heat from the anode and dissipates it in the case. Dental heads are probably one of the safest sources for amateur xrays, they are relatively low power and very well shielded and the HV is self contained. They can still be very dangerous if used carelessly but it's much safer than playing with bare tubes. Xrays are very high energy photons, they can burn your skin very much like intense sunlight, except that they pass through you and burn all the way through, and smash up your DNA in the process. You don't want that! |

Some more results of gameboy cartridges: All 1 second exposure, f2.8, 1st image 3200 iso, 2nd 1600, 3rd & 4th 800. https://imgur.com/a/JReAx |

What are the other parts we're looking at? Looks like some kind of carpet in a closet. Other than that, very cool! And like everyone says, be safe! These are very cool experiments, but a false move can be costly. Be mindful of every step you take. |
