Nuclear Science

Nuclear science is the study of sub-atomic particles and their application in various disciplines. Here you can learn about nuclear power plants, atomic theory and radiation.


How easy is it to steal a nuclear bomb?

If you watched "24," you might think real-life Jack Bauers stop bad guys from detonating stolen nukes all the time. Just how hard is it to steal a nuclear weapon? See more »

How the Manhattan Project Worked

Dropping atomic bombs on Hiroshima and Nagasaki ended World War II. How did the most powerful weapon in the world get developed? It started with the Manhattan Project. See more »

Can people get poisoned by indirect exposure to polonium-210?

British authorities have found traces of polonium-210 in at least five buildings and three British Airways jets since Alexander Litvinenko fell ill. See more »

What's a uranium centrifuge?

Iran has announced its activation of a second set of uranium centrifuges. These machines are at the core of the uranium-enrichment process. Find out where the centrifuge fits into the equation. See more »

How Nuclear Fusion Reactors Work

Fusion reactors will use abundant sources of fuel, will not leak radiation above normal background levels, and will produce less radioactive waste than current fission reactors. Learn about this promising power source. See more »

How Atom Smashers Work

Atom smashers tell us about the fundamental structure of matter, the forces holding it together and the origins of the universe. Discover how scientists use particle accelerators to break atoms apart to learn about the nature of reality. See more »

How Nuclear Medicine Works

Nuclear materials get used in many forms of nuclear medicine -- everything from PET scans to chemotherapy uses them. Learn how nuclear medicine works. See more »

How Nuclear Power Works

On one hand, nuclear power offers a clean energy alternative that decreases fossil fuel dependence. On the other, it summons images of quake-ruptured Japanese power plants belching radioactive steam. What happens in reactors in good times and bad? See more »

How Nuclear Radiation Works

Nuclear radiation can be extremely beneficial or extremely harmful -- it all depends on how it's used. Learn what nuclear radiation is all about. See more »

I once saw this device shaped like a light bulb. It had a vertical support inside it, and on that support there were four vanes with four diamonds on the end. One side of the diamond was black and the other was white. I did a little research and found out that it was called a Crookes' radiometer -- how does it work? See more »
