Oral Presentation

For its ultimate success, the zero-pollution ambition of the European Green Deal requires highly sensitive and state-of-the-art detection techniques to determine ultra-low amounts of pollutants in the environment. Mass spectrometry has become a key method for the determination of non-radioactive polluting elements, and is also of increasing importance for the detection of long-lived...

Oral Presentation

Actinide-AMS has grown into an important discipline for environmental and geological sciences, for oceanography, but also nuclear (astro)physics. Nuclear data requests in nuclear physics continue to challenge the present limits in accuracy and abundance sensitivity of actinide detection. Exploring these limits is the primary motivation of this presentation.
In recent years, significant effort...
