Application

The spectrometer AT1316 (chair-type) is intended for studying the energy distribution of gamma radiation, identify gamma-emitting radionuclides and also for measuring the activity of gamma-emitting radionuclides incorporated in the whole body and lungs.
Spectrometer is a stationary laboratory measuring instrument, which also can be placed in a special vehicle of a transportable laboratory.

The operation principle of spectrometers is based on the registration of gamma-quanta emitted by radionuclides contained in the human’s body by an appropriate type of detector, which outputs an electrical impulse with amplitude, which is proportional to the energy of the detected gamma-quantum.
The spectrometer AT1316 is calibrated by whole body phantoms (universal or anthropomorphic) or using by software MCC-MT (Monte-Carlo simulation).

The energy range of measuring distribution of gamma radiation :   50 to 3000 keV.
The relative energy resolution of the spectrometer for the line 661.7 keV of radionuclide Cs-137 does not exceed  9%.
The integral nonlinearity of the spectrometer with gamma detectors is ±1.0% in the energy range of 50 to 3000 keV.
The detection efficiency of the detector BDEG-150-100 is no less than 7.5% in the full-energy peak 661.7 keV of radionuclide Cs-137 at 50 mm from the upper surface of the detector.


The measurement ranges of activity of incorporated radionuclides with the external gamma background with ambient dose rate of no more than 0.2 µSv/h :
   - Cs-137 in body : from 80 Bq to 750 kBq;

   - Cs-134 in body : from 60 Bq to 400 kBq;
The expanded uncertainty for the activities measurement is no more than 15% (k=2).


The minimum measurable activity (MMA) for measurement time 3 min:
   - Cs-137 and Cs-134 in body : 300 Bq.

Operation mode setup time : up to 10min
