LUNG COUNTER

LUNG COUNTER
LUNGS BURDEN ANALYSIS/COUNTING SYSTEM

The LUNG COUNTER monitor has been designed to perform high-efficiency, fast and reliable radiometric controls of human lungs.

The monitor is composed of:

  • a mechanical support table, featuring up/down movement to align the detectors to the desired height
  • two 5”×4” NaI(Tl) scintillators, mounted on a small rail allowing manual, independent, left/right movement of each detector
  • a laptop with proprietary software managing the system
  • a comfortable chair with armrests and footrest

The detectors include photomultiplier tubes, and they are coupled to independent electronic units providing high voltage to the PMTs, and dedicated MCA modules allowing on-line gamma spectrometry.

 
The system is controlled and managed by a proprietary software installed on a dedicated laptop.

The LUNG COUNTER software implements response function curves for each NaI(Tl) detector. These curves allow converting net counts rates acquired by the detectors (cps) in activity (Bq) homogeneously dispersed in the lungs, and to subsequently evaluate the committed effective dose (in Sv). The response curves are calculated by means of Monte Carlo simulations.
