In this project, students will use their knowledge of nuclear chemistry to read primary sources and write a claim, evidence and reasoning statement to support their determination as to whether the Tokaimura Nuclear Accident was the result of company or worker negligence. In this activity, students analyze a series of graphs and data points to discover a pattern, and realize the meaning of a half-life. During this investigation, students will make connections between the concepts of nuclear decay, radiation and the Law of Conservation of Mass. In this activity, students will analyze a scenario about the sudden spike of lung cancer cases in a specific neighborhood.

The Kinetics of Radioactive Decay and Radiometric Dating - Chemistry LibreTexts
One example of radioactive dating is carbon dating. Carbon dating can be used on anything that was once alive, be it plant or animal. A couple of wonderful examples have been in the news in the past years. When bone fragments are found that are believed to be human or human-like, carbon dating is often used to determine the approximate age of the remains. Another fascinating example is the Shroud of Turin you might check this out on the Internet.
The radiocarbon dating method is based on certain assumptions on the global concentration of carbon 14 at any given time. One assumption is that the global levels of carbon 14 also called radiocarbon in the atmosphere has not changed over time. The other assumption is the corollary of the first; the biosphere has the same overall concentration of radiocarbon as the atmosphere due to equilibrium. The carbon 14 produced reacts with oxygen atoms in the atmosphere to form carbon dioxide.
Radioisotopes of elements have a wide variety of uses. Every living organism contains the radioisotope carbon Carbon is formed when neutrons from cosmic radiation collide with nitrogen atoms in our atmosphere forming protons and carbon atoms. Carbon dioxide is responsible for carbon entering the food chain. Carbon decays by beta-emission and has a half-life of years.
