secular equilibrium การใช้

An alternative is to store specimens in gas tight transparent containers in which radon will accumulate and decay to secular equilibrium.
The 44 Ti / 44 Sc generator represents a secular equilibrium system with a half-life ratio between parent and daughter of ca . 130 000.
The quantity of radionuclide B when secular equilibrium is reached is determined by the quantity of its parent A and the half-lives of the two radionuclide.
In contrast, uranium is soluble to some extent in all uranium-lead system ), thorium-230 instead approaches secular equilibrium with its radioactive parent uranium-234.
Instead, the uranium-thorium technique calculates an age from the degree to which secular equilibrium has been restored between the radioactive isotope thorium-230 and its radioactive parent uranium-234 within a sample.
