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.
Specifications:
Measurement range of thermal neutron flux density | N/(cm2×min) | 10 – 105 |
Measurement range of fast neutron flux density | N/(cm2×min) | 50 – 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 range | eV | 0.025 – 14·106 |
Neutron radiation sensitivity of: | (pulse×cm2)/(neutron) | 4.5 |
-fast neutrons | 13 | |
-thermal neutrons | ||
Maximum gamma radiation exposure dose rate that does not introduce additional error in measurement of neutrons flux density | mR/h | 10 |
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 |
