$^{236}$U (half-life 2.34$\times10^7$ y) is a radioisotope of uranium of key importance for tracing the movement of nuclear waste through the environment. Accelerator mass spectrometry (AMS) is the most robust and capable method for measuring $^{236}$U, which has a natural abundance range between 10$^{-8}$ to 10$^{-12}$ or lower. Here we study $^{236}$U uptake in biota samples (plants,...

90Sr (t1/2 = 28.80yr) has a relatively long life and due to its chemical similarity to calcium, 90Sr accumulates within the skeletal structure of animals and some plants. The aim of this work is optimize a methodology to determine stable Sr and 90Sr in environmental samples including plants, insects, animals and water. The 88Sr was measured by ICP-MS Triple Quad (8800, Agilent Technologies)...

For several years, THz spectroscopy and imaging have been applied to many different fields. However, some burdens still remain in its commercial generalization, particularly for the industry sector. One of these difficulties lies in the acquisition time. In a typical THz time-domain spectroscopy system (THz-TDS), the THz pulse is sampled in time by the means of a micrometer linear delay line....

²³²Th is expected to be the major internal dose contributor for nuclear workers in the development of new Th fuels. Since new fuels are usually processed in the same facilities as U fuel is handled, U might also be a significant internal dose contributor. The development of rapid and sensitive analytical methods for the determination of these elements at the levels observed in bioassay samples...
