Radioactivity has a wide range of uses, including nuclear power, in medicine, and in dating organic and geological samples. It is also potentially dangerous, as high-energy particles and radiation can damage and kill cells, and alter DNA, causing cancer. Radioactive Decay Unstable atomic nuclei ...
Since its discovery in 1896 by physicists Henri Becquerel, Pierre Curie, and Marie Curie, radioactivity has provided clues to the laws that govern nature. Today, the DOE Office of Science supports nuclear decay experiments to answer fundamental questions like: Why is there more matter than anti-m...
Radioactivity is the radiation that is released from an unstable atomic nucleus. Atoms of uranium and plutonium are naturally radioactive atoms.
decays. Thus, the term “decay” habitual in scientific and public use is not worth treating literary to the radioactivity phenomenon, but it should be considered as a synonym of the term “transformation”. In such a sense, the terms “beta-decay”, and “gamma-decay” should be treated....
Is Radioactivity Always Harmful? Conclusion Radioactive decay is a nucleus’ journey to attaining stability via emission of highly energetic radiation and subatomic particles. This phenomenon is called radioactivity. Our brain’s response to the word “radioactivity” often veers into the world of super...
Determine: (a) What are alpha and beta particle? (b) What are x, beta, and gamma rays? (c) What is radioactivity? When were gamma rays discovered? What radioactive isotopes were released in Chernobyl? What type of electromagnetic radiation is used in UV-vis spectroscopy?

Radioactivityis a measure of the rate anatomic nucleusdecomposes into pieces that are more stable. It's somewhat complicated, trying to determine relative radioactivity because there can be many unstable steps in the decay process before an element finally breaks into stable pieces. All of theelement...
