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...
Emily has taught science and has a master's degree in education.Cite this lesson This lesson explores radioactivity by describing sources of radioactivity, how it is used by scientists, and how objects become radioactive. Many objects are radioactive, but a further look will show the small part...
There are parts of the world that are hotter than normal (like Florida) and people live there just fine. Similarly, there are places in the world with higher natural radioactivity due to local geology, like Ramsar Iran with over 100 mSv/yr or Denver Colorado where cosmic rays give 2x more...
Science Chemistry Radioactive decay What is radioactivity in nuclear physics?Question:What is radioactivity in nuclear physics?Nuclear Physics:Nuclear physics is a specialized field in physics that focuses on the nucleus of the atom and the interactions or reactions that occur in the nucleus. This ...
What branch of science is nuclear physics? What is angular momentum in nuclear physics? What does the quantum mechanical model determine about electrons? What is radioactivity in nuclear physics? What is binding energy in nuclear physics?
Another way of thinking about radioactivity is in terms of energy. A radioactive atom has a higher energy than it needs to have. Energy in the universe tends to spread out, and so when something has more energy than it needs, it's only a matter of time until it loses that energy. Wh...
