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.

Measurement range of thermal neutron flux densityN/(cm2?min)10 – 105
Measurement range of fast neutron flux densityN/(cm2?min)10 – 105
Main relative permissible error limit of thermal and fast neutron flux density measurement when calibrated for Pu-Be with 0.95 confidence probability%20+200/N,where N is a numeric value of measured neutron flux density
Registered neutron energy rangeeV0.025 – 14·106

Neutron radiation sensitivity of:
-fast neutrons(pulse?cm2)/4.5
-thermal neutrons(neutron)13.0
Maximum gamma radiation exposure dose rate that does not introduce additional error in measurement of neutrons flux densitymR/h10.0
Operating temperature range°С-25…+55
Additional permissible error limit of measurement, caused by ambient temperature change from -25 to +55 °C%5 per each 10 °C
deviation from 20 °C
