The Special Techniques service is in charge of the following activities:
- development of detection techniques for low-level radioactivity and rare nuclear processes;
- measurement of building and construction materials as regards their content of natural radioactivity;
- measurement of natural radioactivity in environmental samples;
- support to the experiments on usage and maintenance of vacuum systems;
- support to the experiments on usage and maintenance of dilution refrigerators and helium liquefiers;
- Radon monitoring with active radon detectors.
The measurement techniques employed are gamma-ray spectroscopy with several high purity Germanium detectors, alpha spectroscopy with silicon PIPS detectors, and alpha/beta spectroscopy with a liquid scintillation counter.
Since 2006 the laboratory is participating regularly to international intercomparison exercises organised by international accredited institutions (NPL (England), IAEA).
