BNS-298
SURFACE BETA-CONTAMINATION TRANSMITTER
BNS-298 SURFACE BETA-CONTAMINATION TRANSMITTER

APPLICATION FIELD

Determination of surface activity by measuring beta radiation in intensive gamma-background after
  • defect or accident in a nuclear power plant,
  • atomic blast.

CHARACTERISTICS

  • In situ gamma and gamma + beta measurements on large surface with registrating the place of the measurement at the same time,
  • Determination of beta surface activity on subtraction principle even in the case when the disturbing gamma-background is several hundredfold of the dose-effect coming from the surface,
  • Measuring range comprehending six orders of magnitude,
  • Measurement start from a distant computer,
  • Automatic measurement time,
  • Environment-proof housing.
BNS-298 DECO contains two transmiters with the same construction, one detector of which measures only gamma-radiation with beta-filter while the other one measures total gamma+beta radiation. In every 2 seconds the transmitters calculate the dose-effect of the caesium equivalent, the data of the measuring error and the time that has passed from the begining of the measurement and send these survey data to the BETADECO software on request through serial line. The software does subtraction, the value of beta-activity and determines its error. The automatic measurement continues as long as the statistical error drops under the given value or the detection limit decreases below the preset value or the allowed maximum measuring time passes. Besides, user can make adjustments, calibration, tests and visualizations as well as storing survey data and results with BETADECO software.
