PANDA (Particles And Non-Destructive Analysis) is measuring system developed for non-destructive analysis of samples for safety, security and safeguards. The capabilities of the PANDA device were expanded by the addition of a thick silicon detector f

An electron spectrometry set-up was built at IRMM consisting of a vacuum chamber with a moveable source holder and windowless Peltier-cooled silicon drift detector (SDD). The SDD is well suited for measuring low-energy x rays and electrons emitted fr

Equipment was recently developed for detecting alpha particles from flat and smooth surfaces with good energy resolution at ambient air pressure. In this work, the detection efficiencies were determined using different extended-area sources emitting

Rapid detection of alpha-particle emitting radionuclides from liquids doped with (209)Po and (241)Am was investigated. These nuclides may mimic or be among those that could be used as threat agents in malevolent actions such as deliberate poisoning o

Three in situ alpha spectrometry methods were demonstrated to rapidly detect alpha-particle emitting radionuclides from a liquid sample. The liquid containing natU and 241Am was evaporated under an infrared lamp and the residue was analyzed in a vacu

An alpha spectrum containing peaks of radon progeny and measured from a membrane air filter in a vacuum using a high-resolution spectrometer was thoroughly analyzed. The goal was to find solutions to several pending issues in spectrum analysis that a
