BDPN-07

Detecting Unit of Neutron Radiation

• Supplied after metrological testing
• Measures thermal and fast neutrons flux density (or equivalent dose rate on request)
• 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 (or equivalent dose rate on request). 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.

Specifications
