This is a LARGE 7.5x2.5x2.5cm and heavy sodium Iodide scintillation crystal. It is water clear RAW CRYSTAL as pictured. These crystals were salvaged from a very high end gamma camera detectors that had serious engineering problems. It is a raw crystal that could be easily glued to any of my PMT tubes high grade optical cement in a dry air or nitrogen purged glove box. This crystal is very, very hygroscopic and is shipped vacuum packed to keep it fresh until you need it. It has an energy dependent response making the material very useful for miniature nuclear spectrometers and the like. If you are willing to do the work, this crystal will make a detector far more sensitive than even large chunks of plastic scintillator, and many 1000's of times more than a similar sized geiger tube. Instructions for potting this crystal and building the probe assembly will be suppled. These crystals alone sell for over 500 dollars each, and are very hard to find- I have lots of laser and other unique stuff for sale this week.
