and the sum of the protons and neutrons gives the atomic mass, the number of neutrons defines the isotope of that element. For example, most carbon (≈ 99 %) has 6 protons and 6 neutrons and is written ...

An international collaboration of scientists working with the FAIR Phase 0 program at the GSI Helmholtzzentrum für ...

Are there any special safety concerns for any of these isotopes? (Example, tritiated water (3H2O) absorption through skin) Am I familiar with the experimental protocols for these isotopes? Have I been ...

and the time it takes for one-half of a particular isotope to decay is its radioactive half-life. For example, about 1.5 percent of a quantity of Uranium 238 will decay to lead every 100 million ...

Stable isotopes can be used by measuring their amounts and proportions in samples, for example in water samples. Naturally-occurring stable isotopes of water and other substances are used to trace the ...
