PACKAGE RADIATION MONITORING SYSTEM Model # PIM-23B FEATURES: * AUTOMATIC DETECTOR SYSTEM FOR PACKAGE CONVEYOR * RADIATION TRIGGER POINT IS CONTINUOUSLY ADJUSTABLE * MANUAL OVERRIDE * FIVE ENERGY (REGIONS OF INTEREST) WINDOWS SYSTEM DESCRIPTION: The PIM-23B monitors packages while they are traveling on a conveyor belt. Model PIM-23B Package Radiation Monitor is a sturdy, dependable, long life mechanical system with advanced electronics. The detector is a 3" x 3" NaI Scintillator (Optional: 5" or 7" diameter) has its own electronics to give the greatest sensitivity. Numerical measurement results are saved to the 60 Gig hard drive and are easily accessible for all packages: clean and radioactive. PIM-23B Color LCD computer monitor shows measurement values from all 5 Energy Isotopes. Indicating lights show status as "CLEAN" or "RADIOACTIVE". The date, time and results of all data that day, that week and that year are available for display. print-out and safe storage. Accessories: One set of calibration sources is supplied with PIM-23B Package Monitor. This consists of one each Ba-133, Cs-137, Co-60 calibration source standards. Each Source comes with NIST Traceable calibration certificate, test data, and Calibration Factors. SPECIFICATIONS: Conveyors: Packages pass beside the detector, display shows status as "CLEAN" or "RADIOACTIVE/CONTAMINATED". Detector: Spectroscopic Grade 3" x 3" NaI Scintillation Detector. (Optional: 5" or 7" diameter) Ultimate Sensitivity: 7$\mu $R/hr above background in 1 second. Background: Automatically subtracted. Shielding: 2 cm lead over greater than 2$\pi $. Lead shield is modular and easy to assemble (no piece over 65lbs.) Electronics: The Scintillation Detector has its' own PM tube. PMT base (dynode string circuit) Independent Modular high voltage and pre-amp discriminator. This provides improved sensitivity and easier maintenance if a PM tube is replaced.
