The RIMS-setup at the University of Hannover uses multiple grating-tuned Ti:Sa lasers to access a range of resonant ionization schemes. Combined with mass spectrometry, the method can detect actinides in single radioactive particles from the environment, down to 107 atoms of a single isotope [1]. In micron-sized particles from the Chornobyl exclusion zone, the relative 238Pu content can be...

In radioecological studies, the plant uptake and distribution of radionuclides are of major interest for risk assessment. In the present work, the elemental distribution within the tissue of plants is imaged by resonant laser secondary neutral mass spectrometry (rL-SNMS). This technique combines a commercially available time-of-flight secondary ion mass spectrometry (IONTOF TOF.SIMS 5) with a...

MetroPOEM [1] is committed to developing SI-traceable mixed element reference materials for the calibration of mass spectrometric devices. In nuclear forensics, elemental selectivity and precise spatially resolved mass spectrometry is essential for ultra-trace analysis of environmental samples. Resonant laser secondary neutral mass spectrometry (rL-SNMS) combines both element selective isotope...
