In accordance with previous work, the abundances of Rb and K in type I is greater than in type III; Sr is relatively constant. An isochron constructed a Rb-82 doses are averages of rest and stress dosimetry data (see Senthamizhchelvan et al. 1,2 ). To calculate organ doses (mrem) from Rb-82, multiply the dose coefficient for each organ by the administered activity in mCi. b Sr-82 and Sr-85 doses are calculated using software package DCAL and ICRP dose coefficients. Rb - Rubidium 38. Sr - Strontium 39.

Increased Rb/Sr in lake sediment corresponding to reduced catchment weathering is in striking contrast to Rb/Sr decrease in the glacial loess layers in the loess–palaeosol sequence. 2013-02-15 · The Rb–Sr data for each sample and the corresponding isochrons calculated using Isoplot 3.70 (Ludwig, 2008) are given in Table 4 and Fig. 3. Unlike the 40 Ar/ 39 Ar ages which are around 750 Ma, various apparent isochron ages from 600 Ma to 900 Ma were obtained for the three samples using the Rb–Sr method.

2014-04-22 The Rb-Sr method is commonly used to date Rb-rich minerals such as muscovite, biotite and K-feldspar; these minerals usually do not incorporate much Sr at the time of their formation (Goldschmidt’s rules). When the SR (green) line is outside the channel and crosses down with the Upper Limit (blue line) and this line with the SR-Signal line, a strong sell signal is given.

2021-02-24 Rubidium-82 (82 Rb) is a radioactive isotope of rubidium. 82 Rb is widely used in myocardial perfusion imaging.This isotope undergoes rapid uptake by myocardiocytes, which makes it a valuable tool for identifying myocardial ischemia in Positron Emission Tomography (PET) imaging. 82 Rb is used in the pharmaceutical industry and is marketed as Rubidium-82 chloride under the trade names RUBY-FILL Although the unreliability of the Rb-Sr method for dating is readily demonstrated, 1,2 it is important that alternative models are developed to explain the observed patterns of strontium isotopes. The ratios of 88 Sr, 86 Sr, and 84 Sr, relative to each other, are commonly believed to be invariant throughout Earth materials.

Increased Rb/Sr in lake sediment corresponding to reduced catchment weathering is in striking contrast to Rb/Sr decrease in the glacial loess layers in the loess–palaeosol sequence.
The ratio is commonly expressed as 87 Rb/ 86 Sr, where the unstable Rb-87 isotope is referred to as the parent nuclide, being approximately 27 % of all rubidium. The daughter nuclide (Sr-87) is represented by Sr-86, which is stable and not subject to radiogenic The Rb/Sr System.
