Laboratorio Radiométrico Portátil AT1135

AT1135AT1135 Portable Radiometric Laboratory is a hand-carried measurement instrument of spectrometric type and is designed to determine relative activity of 134Cs, 137Cs and 40K gamma-emitting radionuclides in food products as well as in-situ measurement of ambient gamma radiation dose rate equivalent.

 

 

 

 

 

Descripción

The unit has scintillation detector with NaI(Tl) crystal Ø of 25x40mm 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 "HomeRadLab" Software.
When the unit is in dosimetry mode (Detection unit is not covered by lead protection) highly sensitive detector delivers instant response to the slightest ambient radiation level change relative to natural radiation background and its correct measurement. All measurements and processing results are displayed on PC monitor in real-time.
