Method design and validation for the determination of uranium levels in human urine using high-resolution alpha spectrometry

Adsorptive stripping voltammetry of uranium: elimination of interferences from surface active substances and application to the determination in natural water samples

“…Various analytical procedures based on the use of different instrumental techniques have been developed for the determination of U(VI): principally atomic absorption spectrometry with flame and graphite tube atomizers, 6,7 inductively coupled plasma optical emission spectrometry, 8,9 inductively coupled plasma mass spectrometry, [10][11][12][13] X-ray fluorescence spectrometry 14,15 and neutron activation analysis. 16,17 Nevertheless, these techniques require costly and complicated apparatus, which is not available in small laboratories, and are often characterized by high detection limit.…”

Electro-Precipitation of Actinides on Boron-Doped Diamond Thin Films for Solid Sources Preparation for High-Resolution Alpha-Particle Spectrometry

“…Alpha-particle spectroscopy is commonly used for applications in various fields such as nuclear [1][2][3][4], environmental [5][6][7][8], artistic [9,10], and biological [11][12][13][14] samples. Conventional approaches for the preparation of alpha-particle sources generally include (i) radiochemical separation and purification [15,16], (ii) preparation of weightless and thin solid source onto a suitable backing material [17][18][19], and (iii) alpha-particle spectroscopic measurements under vacuum conditions using solid-state semiconductor detectors [20][21][22][23][24].…”

Alpha-particle spectrometry for the determination of alpha emitting isotopes in nuclear, environmental and biological samples: past, present and future

“…Alpha-particle spectrometry (AS) is an important analytical technique for the determination of trans-actinium and other aparticle emitting radionuclides, with high sensitivity in nuclear, environmental and biological samples. [1][2][3][4][5][6][7][8] This radiometric technique is based on the characteristic a-particle energy of each a-emitting radionuclide, and thus can be used for the qualitative and quantitative analysis of different a-emitting radioactive isotopes of an element. The unique features of AS compared to other radiometric techniques like g-ray spectrometry are very low background, and no variation in the detector efficiency with energy (4 MeV to 9 MeV) because of the short range of a-particles.…”
