ERASMUS+ exchange with Kazakhstan / 1.10.2021

The overall objective was to strenghten the collaboration with Al-Farabi KazNu in the field of environmental radioactivity and gamma spectrometry, development of new approaches in teaching of gamma spectrometry techniques and methods.

During the period of teaching activity (19.-27. 7. 2021) Assoc. Prof. Dr. Radojko Jaćimović presented three lectures:

  1. Set-up of an HPGe detector at JSI using Maestro-32 software
  2. Absolute calibration of an HPGe detector using KayWin software
  3. Determination of natural radionuclides in Soil/Sediment samples

Besides the lectures, Dr. Jaćimović gave practical instructions to the participants at Al-Farabi Kazakh National University and they were able to set-up their HPGe detector using Maestro-32 software. During the proposed period, the participants successfully made energy calibration of the HPGe detection and its resolution curve (FWHM – Full Width at Half Maximum). Unfortunately, it was not possible to prepare an absolute calibration of the HPGe detector due to the insufficient number of existing calibration point sources in the lab.

It should be mentioned the during this teaching period, Ms Nurgul Nursapina (PhD student) was a visitor at Jožef Stefan Institute and Dr. R. Jaćimović provided her more information about the possibility to use different gamma spectroscopy software as well as evaluation of gamma spectra (simple and relatively complicated examples) using HyperLab 2014 software.
