WOW! A 3" Scintillator for less than $300.00

I have sold many very sensitive custom built Scintillator Detectors to happy customers

Please Check my FEEDBACK and other items.

This is a 3 inch X 3 inch X 2.25 inch (75mm square) Scintillation Detector designed for GAMMA Radiation Detection. This probe has been newly manufactured in the iRad shop and lab. It is 10 inches in length and weighs 1 pound 12 ounces.

The Scintillator uses a Bicron/Saint-Gobain BC412 Polyvinyl Toluene & Organic Fluors (Plastic) Scintillation Crystal for Gamma Radiation Detection. The crystal is polished on all sides and coated with a specially formulated reflective coating before coupling to the PMT. The PMT is a socketed Burle S83079EM5 Photomultiplier Tube and includes a 62 MegOhm iRad Integral Socket Assembly installed on the probe. After assembly the probe is encased in a Black Polyolefin Tube that is quite durable. It has been tested from 800v to 1100v and runs very well throughout that range of voltage  with excellent sensitivity even at 900v. 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 probe is over 3000+ CPM at 900v. Pictures show detection of Cs137 and Thorite Ore. The probe is shown operating on a Ludlum Model 3 at 900V as calibrated on my Ludlum 500 Calibrator. The probe also ran perfect on my Ludlum Model 18, Model 12, Model 2241-2, Model 2200 Scaler, and Eberline RM-20 all at 800 - 1100v. Voltage on your meter and specific probe may vary slightly. 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 in soil samples, water, milk, fish, vegetables or most anything else you might encounter. Since the Probe is rugged and Non-Hygroscopic, it is great for mineral hunting and field use.

Probe Dimensions:
Length: 10.5 inches - 265 mm (including BNC connector)
Diameter: 3-1/8 inches - 80 mm
Weight: 1 lb 12 oz - 805 grams

The Scintillator Probe includes a BNC connector for connection to your meter. If you 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. C type (Ludlum) connectors are available on request at additional cost, please inquire before purchase.

Only one Scintillator Detector is included in this listing. No other items shown, including test equipment, cables, meters, test sources, or tools are included.
