AT1322 and AT1322/1 Whole Body Counters

AТ1322 and AT1322/1 scintillation Whole Body Counters (WBC) are fixed instruments for measurement of 131I and 133I radionuclides content in human thyroid gland.
FEATURES
 
  • High examination rate: 3 minutes per person
  • Automatic LED stabilization of WBC energy scale
  • Flexible software control of WBC functions, generation of database and report based on measurement results
  • Compact design
  • USB Counter-to-PC connection
  • Can be operated independently or together with AT1316/AT1316A, as well as part of mobile spectrometric laboratory
APPLICATIONS
 
Measurement of incorporated 131I and 133I radionuclide content in thyroid gland for individual dosimetric monitoring of internal exposure, taking into account age of target person
  • Laboratory for internal exposure monitoring of nuclear power plants and other enterprises staff and citizens in the event of radionuclide ingress into human body
  • Radiation diagnostic laboratories in health care facilities
OPERATING PRINCIPLE
 
WBC operating principle is based on detection of gamma-radiation from 131I and 133I isotopes present in human thyroid gland by spectrometric detecting unit, and processing of instrument spectra on PC by dedicated software tools.
