Nuclear physics measurement technologies are used in many industrial measurement processes. The laboratory should help to make the underlying physical principles understandable. Since handling ionising radiation always involves risks, the subject of radiation protection is an integral part of the education.
- Examination and calibration of electronic personal dosimeters. Personal dosimetry, radiometry - application example: Weld seam testing with γ- or X-radiation.
- Investigation, calibration and application of contamination monitors. In addition to dose control, protection against radioactive contamination is a central concern in radiation protection. Contamination monitors allow quantitative detection of even very small traces of radioactivity, provided that they are handled correctly and calibrated carefully.
- High-resolution γ-spectrometry with a Ge semiconductor detector. γ-spectrometry is ideally suited for identifying different radioactive nuclides. The method is used for monitoring nuclear or nuclear medicine facilities, as well as for the examination of environmental and food samples.
- Density and thickness measurement. Radiometric density and thickness measurements are examples of industrial use. They are used, for example, on rolling mills in the steel industry, or in foil, sheet metal, paper and glass production. Radiometric density measurement methods are particularly suitable for food and petroleum processing.
- Moisture measurements with a neutron probe. The method is based on the particularly strong braking effect of hydrogen with fast neutrons. The method has a wide range of applications. Example: Combined probes for density and moisture determination are used in road construction and civil engineering (Troxler probe).
- X-ray fluorescence analysis. If material samples are irradiated with ionising radiation, the atoms are excited to emit characteristic X-rays. By measuring them, an unambiguous, non-destructive determination of the elemental composition of the sample is possible.
- X-ray computer tomography. Tomography is an analytical method in which objects are trans-illuminated from very many different directions and subsequently the three-dimensional structure (e.g. the density distribution) inside the object can be calculated from the projections with the aid of mathematical algorithms.
