Testing laboratory to determine radionuclide concentrations STS 028
This laboratory is responsible for determining the concentration of radionuclides in environmental and food samples. These tests can also be carried out on other types of samples.
To determine radioactive exposure precisely, the exact nature and concentration of the given radioactive substance (radionuclides) must first be ascertained.
The Radioactivity Group is responsible for identifying the radioactive content of sample material within the accredited testing laboratory STS 028 (EN 45001 / ISO 17025 compliant).
The instrumentation available in the SPIEZ LABORATORY and the analytical testing methods used here make it possible to determine the concentration of radionuclides in the environment (air, water, soil, natural cover), in foodstuffs and in other substances (e.g. materials, consumables).
Instrumental analytical methods are used which ensure the non-destructive identification and evaluation of gamma radiation emissions from the test material. Radiochemical analytical methods are also used to separate the radionuclide from the sample material and then to measure and evaluate any nuclear radiation emission (alpha and beta radiation). In addition, mass spectrometry may also be used to determine the concentration of radionuclides. The testing laboratory has the requisite specialist knowledge and experience in on-site sample testing and assessing the implications of the test results for radiation protection.
The testing laboratory is first and foremost a federal laboratory which specialises in measuring radioactivity. It is also a NATO-nominated laboratory for sampling and determining radionuclide concentration (SIRA: Sampling and Identification of Radiological Agents) and cooperates closely with the United Nations Environment Programme (UNEP).
