A Low‐Power Radioisotope XRF Spectrometer for Detection of Light Elements on Planetary Missions
X-Ray Spectrometry, EarlyView.ABSTRACT Current X‐ray spectrometers for in situ geochemical analysis on planetary missions typically rely either on X‐ray tubes, which demand electrical power and add mass and thermal complexity, or on alpha particle X‐ray spectrometers (APXS) that use rare 244Cm$$ {}^{244}\mathrm{Cm} $$ sources, and come with severe concerns on radiation safety and ...

Portable, Benchtop and Micro‐XRF in Agriculture—Present and Future From the Hardware Perspective
X-Ray Spectrometry, EarlyView.ABSTRACT X‐ray fluorescence (XRF) spectrometry has been an important tool in agricultural studies recently. This technique allows the multielemental, direct, and in situ analysis. The objective of this review is to evaluate the use of XRF in agriculture focusing on plant and soil samples based on indexed articles in the Scopus database from 2020 to ...
