To understand nuclear decay equations. How to measure the activity of radioactive sources. Spontaneously means that the process of radioactive decay can not be speeded up or slowed down by physical ...

Add Yahoo as a preferred source to see more of our stories on Google. The findings of a new study suggest radioactive decay rates — long considered physical constants — are more variable than ...

New research has enhanced scientists' understanding of how free neutrons decay into other particles. The work provides the first measurement of the energy spectrum of the photons that are released in ...

Some nuclei of certain elements decay radioactively into nuclei of different elements. These decays can be useful or annoying depending on the context. This is especially true for potassium-40. This ...

The rise of a new generation of radiotherapies means we will soon need much greater quantities of radioactive atoms. That's ...

In a random moment, all energy is lost. The unstable subject cannot help but decay, slowly but surely, letting go of particles to become stable. It loses itself to become balanced again. This is a ...

Observing the recoil caused by a single radioactive decay could help physicists spot exotic particles and possibly even dark matter. Radioactive decay is ubiquitous. It occurs everywhere on Earth and ...

If you would like to learn more about the IAEA’s work, sign up for our weekly updates containing our most important news, multimedia and more. Radiation is energy that moves from one place to another ...

Prefer Newsweek on Google to see more of our trusted coverage when you search. A battery made of diamonds could power devices for thousands of years, scientists have announced. This battery would be ...

The radiation emitted from unstable nuclei is called ionising radiation because as it passes through matter it can dislodge outer electrons from atoms causing them to become ions. An alpha particle is ...
