In this episode, Hank welcomes you to the new age, to the new age, welcome to the new age. Here he'll talk about transmutation among elements, isotopes, calculating half-life, radioactive decay, and spontaneous fission....

After the Chernobyl Disaster, researchers have been studying the movement of radioactive contamination all over central Europe. Fortunately, that radioactive contamination is decreasing in just about every living thing, except for one...

Once upon a time, there was a lake that was so radioactive, that standing on its shore for more than an hour would almost definitely kill you. Join Olivia to learn how it got that bad in the first place, and what was done to fix it!

Learn the basics about radioactive isotopes. The identity and chemical properties of any atom are determined by the number of protons in its nucleus. As atoms get bigger and heavier, the nuclei get bigger and heavier and the protons need...

The identity and chemical properties of any atom are determined by the number of protons in its nucleus. As atoms get bigger and heavier, the nuclei get bigger and heavier and the protons need a “nuclear glue” to help hold them together....

Radioactivity is the property through which a heavier, unstable nucleus assumes a more stable state by emitting radiation. The process through which a nucleus turns into a stable one is called radioactive decay. But is radioactivity or...

Learn the basics about radioactive isotopes? how they are created? and what chemical reactions are created? Find out more in this video!

All radioactive nuclei have a particular half-life, or the time it takes for their concentration to be cut in half. Given the half-life of one such nuclide, can you find the decay constant, and the fraction of nuclei left over after a...

Radioactive Decay Equations | Radioactivity | Physics | FuseSchool In this video we are going to look at radioactive decay and how to balance the equations that describe them. Radioactive decay equations show us what is produced when a...

Learn the basics about water pollution, whilst learning about environmental chemistry. The substances mankind throws away have polluted lakes, rivers and even the oceans. The United Nations estimate that around 10% of the world’s people...

Stable and Unstable Nuclei | Radioactivity | Physics | FuseSchool How do you know if an atom is stable? In this video we are going to learn about radioactive decay and that unstable nuclei either have too many protons or too many...

What Are Quarks? | Radioactivity | Physics | FuseSchool Find out what quarks are, how they were discovered and why they are very important in relation to protons and neutrons. There are different types of quarks which you'll learn about...

Uses of Nuclear Radiation What have the Hulk and Spiderman got in common? They both gained their super powers because of radiation. Well, in films and comics at least. In real life, radiation has never given anyone super powers. But when...

Half life | Radioactivity | Physics | FuseSchool This atom has an unstable nucleus. Any moment now it may undergo radioactive decay. Any time now... Or it may not! We just don’t know, as decay is a random event. We cannot predict when...
