چکیده
Abstract A reliable and accurate laser ablation multi-collector inductively coupled plasma mass spectrometry (LA-MC-ICP-MS) method was developed for analysis of inhomogeneous samples containing uranium particles or aggregates various enrichments. For the development, a mixed solid standard prepared using 1% 3% 235 U enriched certified reference materials. After screening localization interest, isotopic composition analysed 5-µm sample spot determining accurately precisely constituents. Besides LA-MC-ICP-MS, also measured by large-geometry secondary ion (LG-SIMS) additional verification.

The aim of the study is to better understand where uranium deposits in mice kidneys. The spatial distribution of uranium was examined in the kidneys of C57BL/6 mice using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). Mice were exposed to varying levels of uranyl nitrate in their drinking water. Calibration standards were developed to allow for semi-quantitative measur...
