Much of the radioactivity associated with rare earths comes from the element thorium, which is not a rare earth but is typically found in the same ore.
Radioactivity associated with cell surface, cytoplasm, and nucleus was separated then measured in a γ-counter.
The radioactivity associated with the RBCs and plasma was quantified using an automated gamma counter.
Radioactivity associated with EV71 particles was measured and the relative protein content of EV71 capsid was evaluated by Western blot.
Radioactivity associated with SMA41 3-[14C]-methyl group was distributed throughout DNA, RNA, and protein, the latter macromolecule being the most alkylated.
Then EV71 virions were pelleted, washed for 3 times using PBS buffer (pH 7.4) and the radioactivity associated with them was measured.
EV71 virions were pelleted, washed for 3 times using PBS buffer (pH 7.4) and the radioactivity associated with them was estimated.
Dynamic PET imaging, however, improved identification of extra-aortal structures, as radioactivity associated with bowel content and urine was variable over time.
The ground-level measurement of Be-7 in Japan exhibits the possibility of enhancement in the Be-7 radioactivity associated with the intense SEP event on July 14 , 2000
The reactivity of PEEK(CH2 2CO2H was assayed by activation with WSC, SOCl2 or CDI, followed by coupling to 3H-lysine and liquid scintillation counting of the radioactivity associated with the samples.
Additionally, the content of radioactivity associated with tumor tissues remained constant at 2, 4 and 24 h (2.41, 2.48 and 2.47%, respectively), while it got reduced in other organs.
