Gamma spectrometry is a fundamental technique for the qualitative and quantitative determination of gamma-emitting radionuclides in samples of various types.
Thanks to its high sensitivity and versatility, it is applied in multiple fields, including:

• Environmental radioactivity monitoring, to assess the presence of radionuclides in soil, air, and water
• Internal contamination assessments in healthcare and industrial contexts
• Characterization of materials during the decommissioning of facilities and structures subject to radiological practices
• Food and human-use product controls
