  • Automatic determination of consumability of foods and drinks following nuclear incident
  • Simultaneous measurement of beta and gamma radiation
  • MultiAct software package with user programmable isotope library
  • Simultaneous data acquisition and data evaluation procedures
With the IH-111L user can rapidly obtain several information about the contamination in samples, through the selective measuring of beta and gamma radiation of any radioisotopes of fission or activation origin. The principle of the process is the fact that isotopes having characteristically simultaneous beta and gamma radiation, either with short or long half-life period, can be divided into groups as a function of their energy. Based on the measured radiation in the groups, the instrument compares the activity of the sample with relevant norms and determines if the foodstuff is consumable or not. The device is using compond scintillation detector, the measurement method and the system technological scheme are patented by Gamma Technical Corporation.
