Radioactivity is the process whereby unstable atomic nuclei release energetic subatomic particles or electromagnetic radiation (EMR). This phenomenon can cause one element to turn into another and is partly responsible for the heat of the Earth’s core. Radioactivity has a wide range of uses, ...
Radioactivity - the breakdown of unstable atomic nuclei, releasing radiation - is a fundamental process in nature. It is a process that has been harnessed to provide wide and important applications in science, medicine, industry, and energy production. But it remains much misunderstood - and ...

Radioactivity is the process by which an unstable atomic nucleus loses energy by emitting radiation. While radioactivity results in the release of radiation, not all radiation is produced by radioactive material. The SI unit of radioactivity is the becquerel (Bq). Other units include the curie, ...
Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. What keeps the Earth cooking? A main source...
Chemistry, a field of science, has several branches, including nuclear chemistry. The field of nuclear chemistry is involved in the process where nuclei disintegrate or combine nucleus. The formation of a new nucleus may be natural or artificial with some processes, including radioactivity. ...
radioactivity. Some countries are decreasing their weapons arsenal, but this still requires a safe method to dispose of the radioactive materials, especially to stop nuclear proliferation. In addition, other countries have been developing nuclear programs and the potential risk of detonations is still...
