Non-Traditional Stable Isotopes: Retrospective and Prospective
, 2017Traditional stable isotope geochemistry involves isotopes of light elements such as H, C, N, O, and S, which are measured predominantly by gas-source mass spectrometry (Valley et al. 1986; Valley and Cole 2001).

This unit for dispensing radioactive liquids has been designed to reduce the radiation hazard in handling the weekly consignment of 131I, which usually amounts to 100 mc. The problem was to extract the active liquid from the standard Amersham bottle and to prepare a stock solution from which desired amounts could be dispensed. The apparatus is shown in

The properties of the oxygen isotopes provide diverse examples of progress made in experiments and theory. This chain of isotopes has been studied from beyond the proton drip line in 12O to beyond the neutron drip line in 25,26O. This short survey starts

Mercury Isotopes in Earth and Environmental Sciences
, 2014Virtually all biotic, dark abiotic, and photochemical transformations of mercury (Hg) produce Hg isotope fractionation, which can be either mass dependent (MDF) or mass independent (MIF).

Publisher Summary This chapter describes several methods by which isotopes of uranium and other elements are separated. There are four methods that depend on differences in mass numbers A: (1) ion motion in a magnetic field, (2) diffusion of particles through a membrane, (3) motion with centrifugal force, and (4) atomic response to a laser beam.

This year marks two important anniversaries for radioactivity in the fields of biology and medicine: (1) the golden anniversary of the discovery of radium for use in radiation treatment and (2) the silver anniversary of the use of radioactive atoms for tracing stable atoms—that is, of the tracer atom technic.
