Gamma Activity Monitor

Download Datasheet

These highly sensitive scintillation gamma activity monitors of spectrometric type are designed to measure volumetric (specific) activity of 131I, 134Cs, 137Cs, 40K, 226Ra, 232Th radionuclides in samples.

Description

The Atomtex AT1320, AT1320A and AT1320B monitors operate by analysing pulse-height distribution from the detection unit. Energy distribution parameters are processed in energy windows according to matrix method. The matrix method allows measurements of volumetric (specific) activity for monitored radionuclides based on energy windows count rate. The information processing unit (PU) screen displays measurement results in real time. Detection units can also be connected to a PC. A dedicated software provides documentation capabilities.

For more details, please refer to datasheet.

Selected areas of application:

  • Agricultural products monitoring,
  • Foodstuffs monitoring,
  • Potable water monitoring,
  • Mineral raw materials, construction materials, wood products monitoring,
  • Product, raw material and waste monitoring in mining and oil industry,
  • Radioactive waste and effluent monitoring in nuclear industry,
  • Radiation protective measures in case of nuclear disasters.

Features:

    • Smart spectrometric probe

    • Internal continuous automatic LED stabilisation of gamma counter energy scale, calibration integrity monitoring and automatic calibration with integrated KСl sample

    • Memory function and automatic background subtraction

    • “Energy Windows” algorithm is used for instrument spectrum processing

    • Recording and storing in memory up to 300 measured spectra

    • 20-second radiation control of mushrooms and berries in 10-litre packing box

    • PC with dedicated software can be used instead of data processing unit to provide documentation function
