The operation of the superconducting electron linear accelerator S-DALINAC leads to the fact that plant components are activated and thus must be treated as radioactive materials in the sense of the Radiation Protection Ordinance. In order for these plant components to be released back into the normal waste management cycle after their activity has subsided, a so-called release is required, the basis of which is a suitable measurement (clearance measurement) of the activity of these plant components. The aim of the mini-research is the construction and commissioning of a measuring station with the help of which the free measurements can be carried out. The challenge is to assemble, build and commission suitable modules for the envisaged sodium iodide detector. Then the detector system has to be calibrated and characterized. Finally, the first samples are to be measured.

Learning objectives: Digitization of analog signals from a gamma detector, operation of data acquisition modules of the NIM standard, operation of a sodium iodide detector, release procedures in radiation protection.

Prerequisites: Interest in measurement electronics for nuclear physics measurements.
