Build an X-Ray Machine
Following some basic precautions, you can safely assemble an amateur X-Ray machine to conduct amazing X-Ray experiments and produce X-Ray photographs. The first and most important thing you'll need in the construction of your X-Ray machine is of course, a tube to produce X-Rays. Professional X-Ray tubes produce tremendous amounts of X-Rays, are very expensive, and require licensing buy and own.
Fortunately, there is another way to produce X-Rays without the restrictions and expense of a professional X-Ray tube. Certain high power rectifier tubes and receiving tubes produce copious amounts of X-Ray radiation as a byproduct of their normal operation. Not all tubes produce the same amount of X-Ray output. Only about one in ten tubes produces sufficient X-Rays to be useful to conduct experiments with. We carefully select the tubes with the highest X-Ray output from hundreds of high power rectifier receiving tubes. All out tubes are fully tested & guaranteed to produce X-Ray radiation. Simply connect the tube to any high voltage DC power source that can supply at least 20,000 volts and ~presto~ you've got X-Rays.
Our 25 kV High Voltage Power Supply is ideal for powering these X-Ray tubes. We insist safety be put first when assembling any X-Ray device, so we include some of our RadMax® radiation shielding with the tube. Instructions and information are of course also included. For additional shielding, see our Radiation Protection page.
Aside from the amazing hands-on experiments that can be performed, learning the basics of radiation physics and seeing it first hand can be quite rewarding. X-Ray photographs can be produced with this tube using standard 400 speed B&W sheet film. Caution! Never X-Ray any portion of your body or other living thing.
If you're looking for a really unique and impressive Science Fair project, the home built X-Ray machine certainly fits the bill.
Warning: - Overexposure to X-Ray radiation can be dangerous as well as the high voltages that are required to run this tube.
This is not a project for novice experimenters unless they are supervised by someone who is familiar with high voltage equipment and basic radiation safety precautions.
X-Ray tube shown in its most basic operational arrangement. A 25 kV power supply is connected to the tube and it is shown producing X-Rays of sufficient energy to pass through a galvanized steel sheet and register on the geiger counter probe below it.
In typical applications, the tube would be surrounded by a lead shield with small slit or opening in it to permit the X-Rays to exit unimpeded only in one direction.
Equipment shown above is for demonstration purposes only and is not included with the X-Ray Tube.
