Variability of specific activities and specific-activity ratios

Archives of Biochemistry and Biophysics, 1957
Abstract In studies involving the use of specific activities or specific-activity ratios, the amount of the P32 inoculum will apparently have no effect on the coefficient of variation of the results. Dilution of the biological material prior to fractionation, dilution of the digested fractions, or loss of material during digestion will lead to a rise

Investigating Uranium Isotopic Ratios and Activity Ratios in Groundwaters in the State of Idaho

Health Physics, 2018
Analyzing uranium isotopic and activity ratios can give valuable information for hydrologic and environmental studies such as insights to weathering processes, estimating water mixing ratios, and identifying water sources. The authors employed an inductively coupled plasma mass spectrometer (ICP-MS) to perform environmental level concentration ...

Neck-Thigh Ratios of I131 Activity

Archives of Internal Medicine, 1960
Introduction Since radioactive I 131 was first introduced, various isotopic methods—all depending on the fact that I 131 follows the same metabolic pathway as stable I 127 —have been tried for evaluation of thyroid activity. Those tests which have won widest acceptance are those with greatest simplicity of performance without sacrifice of accuracy and
