Gamma spectrometry

Method

Radionuclides in natural and artificial materials can be detected and quantified by α-, β- or γ-spectrometry according to their decay properties. For the non-destructive measurement of short-lived and long-lived gamma emitters of ultra-low and medium activities, we routinely apply γ-spectrometry. This method allows the differentiation of mixed nuclides.

Examples of applications

• Determination of natural and artificial radionuclides
• Dating of sediment or peat with Pb-210 and Cs-137
• Detection of Cs-137 from the Chernobyl disaster in food samples
