FHT 750/751/752 中子探头
These series of neutron dose rate detectors feature excellent energy response and very low gamma interference. Among the three different versions available, a light-weight moderator has been designed for security applications.
BIOREM  FHT 750 is a neutron dose rate detector for stationary and portable use, featuring excellent energy response according to ICRP 60 with special moderator.

It is currently available in three versions:

  • FHT 750 with built-in amplifier and external high voltage supply
  • FHT 751 with completely built-in microprocessor electronic with serial RS-485 interface for networked area monitoring 
  • FHT 752 for connection to Radiameter FH 40 G-L and FHT 6020

For enhanced neutron sensitivity we also build FHZ 752 H incorporating a He-3 tube as detector instead of a BF3 tube:

Neutron response: 2 cps at 1 ?Sv/hGamma response: 1 cps at 10 mSv/h

Energy Range : 0.25 eV ... 10 MeV
Typical Neutron Response : 1cps at 1.8 ?Sv/h
Gamma Rejection : 10^-5 at 1 Sv/h due to BF3 detector
Background : typical 0.001 cps
