Area of Science:

  • Environmental Science
  • Nuclear Chemistry
  • Ecology

Background:

  • Gamma-ray analysis is crucial for characterizing radioactive elements in environmental samples.
  • Evaluating natural and anthropogenic radioactivity is vital, especially in natural reservations and areas with nuclear pollution.
  • The Danube Delta is ecologically significant and potentially impacted by radioactivity.

Purpose of the Study:

  • To determine if gamma spectroscopy can identify patterns in Danube Delta biota, specifically reed.
  • To ascertain the presence of anthropogenic tracers in environmental samples from the Danube Delta.
  • To assess the suitability of gamma spectroscopy for radioactivity studies in this region.

Main Methods:

  • Gamma spectroscopy was employed for radioactive element characterization.
  • Pattern and cluster analyses were utilized to interpret spectral data.
  • High-Purity Germanium (HPGe) detectors were used for sensitive measurements.

Main Results:

  • Gamma spectroscopy successfully identified patterns in reed samples.
  • The presence of anthropogenic tracers was confirmed in the studied biota.
  • Pattern and cluster analyses demonstrated the efficacy of the method.

Conclusions:

  • Gamma spectroscopy is a suitable method for pattern identification in common biota like reed.
  • Anthropogenic tracers can still be detected in Danube Delta biota.
  • Further studies on sediment and trophic chains are recommended to understand radionuclide dynamics and transfer factors.
