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

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
