RadEye NL

RadEye NL Personal Highly Sensitive Neutron Radiation Detector

RadEye NL Personal Highly Sensitive Neutron Radiation Detector closes a gap in the classical product spectrum of the radiation measurement technology. While traditional Rem-Counters are usually heavy and bulky, the RadEye NL detector is compact and lightweight. Users (e.g. service staff) who travel on commercial aircraft can use the RadEye NL as it has a He-3 counting tube with a filling pressure of 2.5 bar.


  • Users of industrial neutron sources (e.g., in geology and material testing)
  • Operators and users of accelerators in medical science and research
  • Radiation protection staff and inspectors of nuclear facilities
  • First responders and law enforcement officers
