Espectrómetro AT6101DR/1

AT6101DR-1AT6101DR/1 Multifunction portable spectrometer is designed for radiation monitoring of water, agricultural produce, seafood, raw material and other material without prior sampling and sample preparation. Measurements are made in 4π geometry by spectrometer's detection device places in the controlled material.
 
Spectrometer capabilities:

  • Identification of 134Cs, 137Cs, 40K radionuclides
  • Measurement of 134Cs, 137Cs, 40K radionuclides specific activity
  • Measurement of ambient gamma radiation dose equivalent rate

 

Descripción

OPERATING PRINCIPLE
 
The unit has scintillation detector with NaI (Tl) crystal Ø63x160mm size inside lead protection. The unit automatically checks sample radionuclide content during sample radiometric radionuclide monitoring. The identification results are used for sample radionuclides activity calculation. Gamma ray instrument spectra are processed in software.
 
All measurements and processing results are displayed on PC monitor in real-time.
