Detecting Unit of Neutron Radiation

Supplied after metrological testing
Measures thermal and fast neutrons flux density
Wide operating temperature range

Description:

BDPN-07 detecting unit is designed to search for neutron radiation sources and measure thermal and fast neutrons flux density. It is used both as a part of the MKS-07 POSHUK search dosimeter-radiometer and within automated systems of radiation monitoring.

Purpose of Use:

Search for neutron radiation sources and measurement of thermal and fast neutrons flux density.
