Radioactive isotopes are nuclides whose nuclei are unstable and radioactive. Radioactive isotopes undergo radioactive decay and emit gamma rays and sub-atomic particles. If all isotopes of an element ...

Tantalum is one of the rarest elements and has multiple stable isotopes. ... Although energetically possible, the radioactive decay of this excited state in Ta-180m has never been observed.

For any substantial sample of a radioactive isotope, half the atoms will decay in a period known as that isotope’s half-life. If you suitably store a kilogram of carbon-14, 5,700 years later ...

An international team of researchers, led by scientists from GSI/FAIR in Darmstadt, Germany, has studied r-process ...

As per the one behind this idea, 30 kilos (66 pounds) of radioisotope could be spread over an area of 250 square meters (2,690 square feet), which should allow a ship to reach a top speed of ...

The topic of atomic structure covers atoms, isotopes, ions, radioactive decay and the uses and dangers of radiation. Part of Physics (Single Science) Atomic structure ...

IN the course of investigations with radioactive isotopes in this Department, anomalous rates of decay have been observed with some isotopes in particular chemical forms. The escape of iodine-131 ...

Some isotopes are stable, while others are radioactive and decay over time, emitting radiation. Carbon-14 is a radioactive isotope of carbon, meaning that it undergoes beta decay, releasing electrons.

Many unstable isotopes give off radioactive energy as they decay. And science and industry have figured out how to put that to use. An isotope of the element fluorine, known as Fluorine-18, is ...
