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
