Supplier:  Thermo Scientific™ 4250678

Catalog No. 19-155-211

Description

Neutrons are used for material characterization in geological and geochemical sciences, material sciences and medical research. Personnel who work with neutron radiation need special instrumentation to monitor their radiation exposure and provide rapid warning of neutron radiation fields. The Thermo Scientific™ Radeye™ NL Personal Highly Sensitive Neutron Radiation Detectors complement passive and active neutron dosimeters and can be easily used by anyone working with industrial neutron sources, staff and inspectors of nuclear facilities, first responders and law enforcement officers.

The 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.

The RadEye NL detector can be worn at the body in an optional holster using the users body as moderator. An optional moderator with handle is available for use outside the holster for search and find applications. A dose rate calibration factor can be entered for use in know neutron radation fields in reference to a calibrated neutron dose rate meter such as a remball.
