BDPA-07

Detecting Unit of Alpha Radiation

• Supplied after metrological testing
• Wide energy range
• Wide operating temperature range

Description
BDPA-07 detecting unit is designed to search for alpha radiation sources and measure surface alpha-particles 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 alpha radiation sources and measurement of surface alpha-particles flux density.

Specifications

• Measurement range of surface alpha-particles flux density
  1 – 105 1/(cm2×min)
• Main relative permissible error limit of surface alpha-particles flux density measurement when calibrated for 239Pu with 0.95 confidence probability
  15+10/А %,where A is a numeric value of measured surface alpha flux density
• Energy range of registered alpha radiation
  4.0 – 8.0 MeV
• Detector
  counters in corona discharge mode
• Mica thickness
  10 – 11 µm
• Alpha-particles detection efficiency
  24 – 32 %
• Window area
  21 cm2
• Operating temperature range
  -25…+55 °С
• Maximum gamma radiation exposure dose rate that does not introduce additional error in measurement of surface alpha-particles flux density
  10.0 mR/h
• Additional permissible error limit of measurement, caused by ambient temperature change from -25 to +55 °C measurement

5% per each 10 °C deviation from 20 °C
