Isotope separators

1980
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.

Mercury Isotopes in Earth and Environmental Sciences

, 2014
Virtually 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).

ISOTOPES FOR MEDICINE

Journal of the American Medical Association, 1948
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.
