ONLY $189.00 NEW & IMPROVED VERSION (shorter and even more sensitive) Now Includes a High Quality Hamamatsu R6233 PMT I have sold hundreds of custom built Scintillator Detectors to happy customers This is a 3 inch Scintillation Detector designed for GAMMA Radiation Detection. This probe has been newly manufactured in the iRad shop and lab. It is just over 7 inches in length and weighs 1 pound 4 ounces. The Scintillator uses a Bicron/Saint-Gobain BC412 Polyvinyl Toluene & Organic Fluors (Plastic) Scintillation Crystal for Gamma Radiation Detection. The crystal 3 inch diameter by 2-1/4 thick, polished on all sides and coated with a specially formulated reflective coating before coupling to the PMT. The PMT is a new high quality Hamamatsu R6233 Photomultiplier Tube and includes a 120 MegOhm dynode chain. After assembly the probe is encased in Black Polyolefin and is quite durable. It has been tested from 650v to 1100v and runs very well throughout that range of voltage with excellent sensitivity at 800 to 900 volts. The detector can easily be swapped out with GM probes that also run at 900 volts without changing your HV settings (on meters that support scintillation detectors). I recommend this probe if you have a Meter with adjustable HV like a Ludlum Model 3 and most all other Ludlum meters. The probe comes with a 30 day Warranty and Satisfaction Guarantee. Background here at sea level for this particular probe was about 3000 CPM at 850v. Pictures show detection of Cs137. The probe is shown operating on a Ludlum Model 18 at 850V as calibrated on my Ludlum 500 Calibrator. The probe also runs perfect on my Ludlum Model 3, Model 12, Model 2241-2, Model 2200 Scaler, and Eberline RM-20 all at 650 - 1100v. Voltage requirements on your meter and specific probe may vary. Background may also vary in your area and instrument. Operating Instructions and directions for adjusting HV and Plateau of detector are included in the sale. This detector can easily detect low levels of Gamma radiation. Since the Probe is rugged and Non-Hygroscopic, it is great for mineral hunting and field use. Probe Dimensions: Length: 7.4 inches - 190 mm (including BNC connector) Diameter: 3 inches - 78 mm Weight: 1 lb 4 oz - 545 grams The Scintillator Probe includes a BNC connector for connection to your meter. If you prefer a C type (Ludlum) connector, these are available on request, please inquire before purchase. If you prefer to keep the BNC connector but need a BNC to C adapter to use this probe with a Ludlum Meter and C Cable, please see my other listings for the connector. I also sell this item as a DIY KIT for those that may want to build it to learn. Please see my listings for this and other kits available. Only one Scintillator Detector is included in this listing. No other items shown, including test equipment, cables, meters, test sources, or tools are included. Expedited Shipping! I ship very fast, same day if early enough, next day otherwise (except Holidays and Weekends). Packaging will be safe and secure, and I guarantee your satisfaction and no DOA.
