For example, most carbon (≈ 99 % ... Stable isotopes do not decay into other elements. In contrast, radioactive isotopes (e.g., 14C) are unstable and will decay into other elements. The less abundant ...

This activity is measured in becquerels. Different radioactive isotopes have different half-lives. For example, the half-life of carbon-14 is 5,730 years, but the half-life of francium-223 is just ...

Oxygen, for example, has eight protons ... which has 20 neutrons. Working at the Radioactive Isotope Beam Factory (note: they do not mass produce little beams and package them up), a team of ...

Even though radioactive isotope dating is generally accurate, researchers still need common reference points in order to compare different sets of samples. For example, researchers studying more ...

An isotope emits gamma rays that easily pass through the body to a detector outside the body, for example a ‘gamma camera’. In this way, the radioactive isotope can be followed as it flows ...

Australia's Open Pool Australian Lightwater (OPAL) research reactor has the potential to “make a real difference” in the effort to deal with the global shortage of radioactive isotopes used ...
