Description
The present work describes the development and implementation of a
methodology for the gamma-spectrometric characterization of metallic samples
irradiated in different neutron fields with energies ranging from 2.4 up to 14 MeV.
The samples studied consisted of a set of disc-shaped metallic elements manufactured
from high-purity materials, including silver, tantalum, cobalt, and nickel. Following
neutron irradiation, the samples were measured using High-Purity Germanium
(HPGe) detectors, while spectral analysis was carried out with dedicated gamma
spectrometry software.
Correction factors were applied on the spectrometric data to account for true
coincidence summing effects and photon self-attenuation within the sample volume.
The activity induced in each sample was then determined from the corrected gamma
spectrometric measurements, enabling a quantitative evaluation of the activation of
the specific metallic elements under the corresponding irradiation conditions.
The developed methodology demonstrates a reliable and reproducible
approach for the quantitative gamma-spectrometric analysis of irradiated metallic
samples. Furthermore, it contributes to the optimization of experimental procedures,
correction protocols, and data-analysis practices employed in neutron-activation
measurements and spectrometry laboratory operations.
