Whole body counter low background WBC-K

         Spectrometric system for whole body counting WBC-K (chamber) is designed for life-time detection of nuclide content and measurement of activity of incorporated gamma-emitting radionuclides and Sr-90 in whole human body as well as for measurement of radionuclides activity in individual organs of human body.
         WBC-K is used for expert examination of radiation accidents victims, persons living in radioactive contaminated areas and staff, working with radioactive substances.
          WBC-K can be used also for assess of gamma-emitting radionuclides activity in large foodstuffs samples in their natural state and in big volume environmental samples.
          WBC-K is a system of high sensitive scintillation and semiconductor gamma-spectrometers of BDEG type placed into large protective chamber with a movable bed for a patient under examination inside it.
         WBC-K operation is carried out under the control of analyzing and computing system providing control of spectrometric tracts, measurement performance, processing of spectrometric information, record of radionuclides activity measurements results and database support of measurements results, as well as control of all drives and automatic systems of WBC-K.
        Principle of operation of WBC-K is based on registration of gamma-radiation from whole body or individual organs of a patient by corresponding detection system. Determination of nuclide content of incorporated radionuclides is performed with use of semiconductor spectrometer of gamma-radiation energy according to measured energies of full absorption peaks registered in instrumental spectra. Measurement of activity of gamma-emitting radionuclides is performed by direct measurement of gamma-radiation of incorporated nuclides, and strontium-90 - by measurement of bremstrahlung of incorporated Sr90-Y90. Calibration of spectrometer for measuring activity of gamma-emitting radionuclides and strontium-90 is made with use standard samples of activity of incorporated radionuclides (phantoms).
