AT1329 Sample Counter

AT1329 Sample Counter

Sample counter is designed for simultaneous or separate measurement of gross alpha activity and gross beta activity in various samples.

Sample counter can be used to:
- Measure gross alpha and gross beta activity of counting samples based on aerosol analytical filters of АФА type
- Measure gross alpha and gross beta activity in "thick-layer" counting samples prepared from sample material (e.g. by evaporation, or any other method of preparing "thick-layer" sample)
- Measure gross alpha and gross beta activity in "thin-layer" counting samples prepared from sample material (e.g. by electrolytic deposition)
- Measure activity, flux density, external alpha and beta radiation for sources of 1П9, 2П9, 3П9, 1С0, 2С0, 3С0 type
- Control radiation contamination of surfaces by a smear method

  • Instrument control and processing of measurement information is realised by external PC
  • Custom calibration settings capability
  • Selectable units of measurement
  • LED stabilization of measurement path
  • Passive background radiation protection
  • Measurement database capability
  • Methodological support of measurements
