Seller: auctionoutletsales ✉️ (6,110) 100%, Location: Camarillo, California, US, Ships to: WORLDWIDE, Item: 291992754930 X-ray Image Intensifier Blue Screen tube photography Fluoroscope . This listing is for one X-ray Intensifier Screen approximately 8x8 inches(20.3x20.3 centimeters) BLUE This screen has a special coating that illuminates under x-rays and can be used for x-ray photography, physics demonstrations, experimentation using the tubes like the one from unitednuclear or any Crookes type tube. The BLUE DARK IMAGES OF A VACUUM TUBE ARE REALISTIC EXAMPLES OF WHAT YOU SEE WITH THE NAKED EYE! They have not been lightened to make the product "look" better. You can lighten digital photos in Photoshop to make them clearer by adjusting the brightness control. A Photoshop lightened image is shown for a multimeter x-ray in the photos so you can see what it looks like when lightened by photoshop.  This is a plastic sheet similar in thickness to cardstock but made of plastic which is impregnated with special rare earth materials. The image shown is the actual material being offered. The photo shows a vacuum tube which was exposed to 70kv 150ma from a medical x-ray machine and this projected the image on the intensifier screen which was placed about one foot behind the tube. The closeup shows the larger projected image. This is due to the magnification effect that happens when the object being x-rayed is a significant distance from the imaging material. You can see that the screen glows brightly and the projected image is amazingly clear. This is an 800 speed screen which is twice as bright as a 400 speed or four times as bright as a 200 speed. That means it will glow brightly with less radiation than would be required for lower rated blue screens. BLUE Intensifier Screen 800 Speed  Size: approximately  8x8 inches(20.3x20.3 centimeters) I ship from the USA. Warning:  Xrays are dangerous. Do not experiment unless you have formal training in their safe use. Do not expose the screen to direct sunlight. It should be stored in complete darkness when not in use. Clean with damp rag only. If needed, clean with mild detergents such as basic soap and water. Do not spray directly with any chemical cleaners. The screen has a protective coating over it but it can be damaged by harsh chemicals. Back may feel slightly tacky which allows you to stick it to a flat board like foam core or thin cardboard. The back side will be marked so you know which side will be most reactive. Blue screens do not appear as bright as the green versions to the eye or the camera but are still very useful for demonstrations. These are salvaged screens cut from larger sections. If you need a larger piece, I can post a special auction listing for a larger size.
