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 ...

Researchers at the Accelerator Laboratory of the University of Jyväskylä, Finland, precisely measured atomic masses of ...

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 ...

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 ...

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 ...

These initial elements consisted of a mix of stable and radioactive isotopes. In the case of iron, for example, the Earth ...

Asking Questions and Defining Problems: Formulating questions about the nature and implications of half-life in various contexts. (Example: Asking questions about how the half-life of a radioactive ...

Stable isotopes are non-radioactive forms of atoms ... Stable isotopes can be used by measuring their amounts and proportions in samples, for example in water samples. Naturally-occurring stable ...
