Super High Quality 1.5” Square ZnS(Ag) over Thin Film Polyester Sheet, used for Alpha Radiation Detection. This listing is for one 1.5-inch (38mm) square sheet Eljen Technology EJ-440 ZnS(Ag) Scintillation Film (size is approximate). This film can easily be cut to shape with scissors and used for building an Alpha Radiation Detector or when making Spinthariscopes for viewing Alpha particle scintillation with the eye.ZnS(Ag) Scintillation Film can be added to the end of a plastic scintillator to make an Alpha/Beta/Gamma Detector, or directly to the end of a PMT to make an Alpha Detector. Simply trace your PMT (or scintillator) to the disk with a pencil and then cut to shape using scissors. They can be attached to a scintillator block and/or PMTs or cut down for smaller scintillator blocks and/or PMTs. They can be built into a housing all by themselves to view Alpha scintillation directly by the naked eye. Much information about making these devices is available on the internet simply by searching “Spinthariscope”.The precut High Quality ZnS(Ag) sheet is ready to be installed over the end of a of PMT or scintillation crystal, then cut to size as shown in the pictures. The picture of PMT and scissors are shown only to demonstrate cutting process. The picture does not represent the size of the film you will receive, nor are the PMT or other items shown included.PROPERTIESEJ-440 Light Output (% Anthracene)300 Wavelength of Maximum Emission (nm)450 Decay Time (ns)200 Phosphor Density (mg/cm2) 3.25 ± 0.25 EJ-440, Thickness of Polyester Film (mm)0.25 EJ-440, Density of Polyester Film (mg/cm2) 36 ZnS(Ag) film is not necessary for Gamma only detectors but are used often for Alpha Scintillation Detectors built with “End Windows”. Two or more layers of Rad-Film (aka Alpha-Film) should also be used over the ZnS disk to block light from entering the detector when used for an Alpha Scintillator. Please see my other listings for other custom scintillation detector parts and related items. I also have alpha-film (rad-film) to fit these here: https://www.ebay.com/itm/253055208452 Need a larger size sheet? Please ask...
