Practical training

Internships
In addition to the Master's internship, it is possible to register for a voluntary internship. In addition to methodological training, specific topics can be worked on as part of our current research work. Here you will find currently advertised topics for internships and student assistantships at the Institute of Resource Ecology.

Analytical internship
For students of chemistry and food chemistry, two radiochemical experiments are offered as part of the practical course “Instrumental Analysis”.

In the experiment “Technetium determination in environmental samples (TCU)”, the technetium content of a water sample is determined using liquid scintillation measurement. In this experiment, which is carried out in modern radiochemical laboratories within a control area, students learn about the handling of open radioactive substances at the tracer level, the use of radionuclides as indicators, the separation method extraction chromatography and, in addition to the liquid scintillation measurement technique, gamma spectrometry for the identification and quantitative determination of gamma-emitting radionuclides.

The “Isotope Dilution Analysis (IVA)” experiment involves the determination of uranium using alpha spectrometry and the calculation of the decontamination factor for 137Cs using gamma spectrometry. 233U is added to a solution of depleted uranium and 137Cs and the uranium concentration of the initial sample is determined using the measured activity ratios. The alpha preparation is produced by electrolytic deposition. The 137Cs is determined by gamma spectroscopy before and after deposition.

The practical experiments are carried out both at the Institute for Resource Ecology (Helmholtz Center Dresden-Rossendorf) and in the central radionuclide laboratory at TU Dresden.
