Model TBM-6GN Gamma Neutron Survey Meter

Low cost MicroR survey meter for Gamma and Neutron Detection

Price: $1750

Features:

• Detects 10 µ R/hr (0.1 µ Sv/h) above background in two seconds
  
• 99% Confidence: four Sigma
  
• Bismuth Germinate Scintillation Crystal gives size and sensitivty breatkthrough
  
• Neutron Detection For Fissle Materials

Application: The TBM-6GN Precision Radiation Proximity analyzer is small with unprecedented sensitivity and accuracy. The TBM-6GN is designed specifically for use by inspectors and guards, police and hazmat squad to give warning in case of illicit or accidental storage or transport of radioactive and fissile material. Suitable uses are for shipment inspectors both in USA and overseas. Also power plants, environmental and industrial inspectors and steel mills. Also in hospitals, landfills and at customs entry and exit points. The TBM-6GN is also useful as a µ R/hr meter.

Description: Small, portable gamma and neutron monitor with Optional shoulder strap and D-Ring. Digital readout of µ R/hr. Alarms on radiation level settable down to background level.

The TBM-6GN alarms at any of 99 preset levels. It also accurately measures exposure dose rate. The dose rate is displayed continuously on the digital LCD display. When the alarm set-point is reached, the beep is continuous until it is reset (front panel button). The TBM-6GN circuitry is completely digital, thus eliminating the inaccuracy inherent in any analog circuit. Calibration controls are recessed and covered .

Neutron Detection : Fissile materials may only emit weak gamma emissions which are hard to detect. These materials also have spontaneous neutron emissions. Detection of even a few neutrons is significant since the natural background neutron count rate is zero. When the neutron indicator comes on the operator knows that neutrons from fissile material are present.
