The Berthold LB 6411 Neutron Dose Rate Probe was designed for the measurement of the ambient equivalent dose of neutrons. It consists of a polyethylene (PE) moderator sphere with a composite 3He recoil proton counter tube at its centre. The system can be operated with the easy to use universal monitor (UMo II) LB 134 or as a stationary system with our data logger LB 115.

The LB 6411 probe is characterized by an extremely high sensitivity of approx. 3 pulses per nSv, more than 5-times better vs. detectors with conventional design. This was achieved by the relatively large detector volume and a special gas filling of the proton counter tube. Thus, additional recoil protons are produced in the counting gas, resulting in enhanced sensitivity.

Features:

• Best-in-class sensitivity: 3 counts per nSv in the energy range of 1 to 10 MeV
  

  ---

• Fast results: Short measuring times in weak neutron fields
  

  ---

• Oustanding flexibility: can be used both, as a portable and as a stationary measuring device
  

  ---

• High data integrity: calibrated to the ambient equivalent dose H*(10) for neutrons recommended by the ICRP 60 and ICRU 39
