understanding radioactive decay and half-life is crucial for explaining the heat generated by radioactive isotopes within Earth’s interior. These Crosscutting Concepts and Science and Engineering ...

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 ...

This could be stated as a fraction, decimal or ratio. For example the amount of a sample remaining after four half-lives could be expressed as: a fraction - a \(\frac{\text{1}}{\text{2}}\) ...

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 ...

In the previous months, she had honed a chemical separation technique for extracting a sizable sample of radioactive ... measuring the half-life of samarium-146. This long-lived isotope and ...

As another plus, this carbon-14 is derived from graphite blocks, which are a byproduct of nuclear fission reactors. So, not ...

An unexpected radioactive discovery beneath the Pacific Ocean seabed may provide researchers with a new global geologic time ...

Researchers at the University of Jyväskylä’s Accelerator Laboratory have created radioactive ... The generated isotopes are difficult to examine because of their short half-life.

Beryllium-10, a rare radioactive isotope produced by cosmic rays in the atmosphere, provides valuable insights into the Earth ...

An unknown 'bump' on a scientist's screen In this work, researchers determined two-neutron separation energies of the lanthanum isotopes and discovered a strong, local increase, a "bump," in the ...
