Short description

Practices include measurements of gamma-ray attenuation coefficients in an energy range of 200-4400 keV for new building materials used in nuclear construction (laboratories, nuclear reactors). Samples of three shielding concretes doped with gadolinium and without admixtures will be tested with the use of a precise semiconductor HPGe detector ORTEC GMX25P4-70. Additionally, the properties of absorbing neutron radiation emitted from the AmBe source will be tested for these materials. The second part of the practice will be modeling of neutron transport in these materials and determining the dose rate absorbed by a human behind a given layer of this material, as well as determining the energy distribution of neutrons and the secondary gamma quanta.

Main research tools

  • detector HPGe ORTEC GMX25P4-70
  • AmBe neutron source

Additional requirements to the candidate

  • Basic skills in data analysis (SMOP-1)
  • Knowledge on the basic processes of gamma quanta interaction with matter

Possibility to continue student internship in the form of:

  • Diploma thesis (master's or bachelor's degree): Yes
  • PhD study: Yes
