decay series

What does that then imply during a decay series?

Boltwood focused on the end products of decay series.

The decay series of uranium-235 (historically called actino-uranium) has 15 members that ends in lead-207.

Such materials become non-radioactive only through the passage of time during the isotopes' normal radioactive decay series.

Its decay series ends with thallium-205.

Francium-223 is the fifth product of the actinium decay series as the daughter isotope of actinium-227.

No radon isotopes occur significantly in the neptunium (Np) decay series.

The radium decay series yields a spectrum of beta particles with a wide range of energies.

In that same year, other research was published establishing the rules for radioactive decay, allowing more precise identification of decay series.

Boltwood gave up work on radiometric dating and went on to investigate other decay series.

Decay chain (decay series): the series of decays that certain radioisotopes go through before reaching a stable form.

Pb-210 is a naturally occurring radioactive element that is part of the uranium-238 Radioactive decay series, and has a half life of 22.3 years.

This type of design results in an extremely simple distortion spectrum comprising a monotonically decaying series of harmonics.

The decay series of U, which is called the actinium series has 15 members, all of which eventually decay into lead-207.

Plutonium-241 is the parent isotope of the neptunium decay series, decaying to americium-241 via β or electron emission.

Other dating techniques using this decay series include uranium-thorium (using Th/U) and uranium-lead dating.

The constant rates of decay in these decay series makes the comparison of the ratios of parent to daughter elements useful in radiometric dating.

Rogers et al. (Fig. 10) instead constructed an electrostatic spectrograph capable of resolving the energy maxima of individual beta particle lines from the radium decay series.

His studies were flawed by the fact that the decay series of thorium was not understood, which led to incorrect results for samples that contained both uranium and thorium.

The white lead in the painting The Supper at Emmaus had polonium-210 values of 8.5 1.4 and radium-226 (part of the uranium-238 radioactive decay series) values of 0.8 0.3.

Since reverberation is essentially caused by a very large number of echoes, simple reverberation algorithms use multiple feedback delay circuits to create a large, decaying series of echoes.

This for the most part harmonic distortion is a distortion with a unique pattern of simple and monotonically decaying series of harmonics, dominated by modest levels of second harmonic.

Beginning with the naturally-occurring isotope U-235, this decay series includes the following elements: Actinium, astatine, bismuth, francium, lead, polonium, protactinium, radium, radon, thallium, and thorium.

Such "decay series", such as the uranium-radium and thorium series, were known within a few years of the discovery of radioactivity, and provided a basis for constructing techniques of radiometric dating.

Uraninite also always contains small amounts of the lead isotopes Pb and Pb, the end products of the decay series of the uranium isotopes U and U respectively.
