In Vivo Counters for Radionuclides in the Human Body

using HPGe (NaI) detectors, with lead, steel & Cu shields, for individual measurement geometries.

Application for nuclear sample mesurements

  • Ultra low-level background in vitro -
    γ-spectrometers (ULB) are designed for
    the direct assessment of extremely low
    sample activities (contaminations).

  • The concept and performance of our ULB spectrometers are designed for lowest limit of detection using the comfort of a ground level laboratory with fast and easy sample change compared to  undergraund labporatories.

In radiation protection for national & international institudes and industry

  • In Universities, research centers, nuclear medicine

  • dustry- and nuclear technology

  • Dismantling, consulting, waste management

  • Environmental, health and food surveillance and laboratories

  • Civil defense, emergency response, border, safety, security and access control

Techniques of Investigation

  • Single detector geometries

    • Chair geometry

    • Arc geometry

    • Scanning with a single detector

  • Multidetector geometries

    • Stationary detector arrays

      • Stretcher geometries (most 4-8 up to 54 detectors)

    • Scanning devices

      • Line scanning devices (most 1 to 4 detectors)

Individual organ or partial body measurements

  • Low energy counters

    • Organ counters

      • Lung counters (most 1-4 up to 8 detectors)

State of the art technology

Install state-of-the-art technology to measure simultaneously
β- and γ-rays as well as Bremsstrahlung in a mobile chamber
applicable for homogeneously and in homogeneously
distributed radionuclides in the human body.

Partial body counter

  • Spectrum-wide shape is formed for each nuclide 

  • For all nuclides full-spectrum shape are summed for best fit

  • VRF is visually driven for reporting, graphing and analysis

  • Energy, resolution and efficiency calibration by best fitting
