Nuclear Chemistry Concepts and Applications

Dr. English introduces nuclear chemistry, focusing on the uses and dangers of radioisotopes. The video covers applications in medicine, industry, and power generation, as well as dating techniques using isotopes like carbon-14 and uranium-238. It discusses the risks of radiation exposure and nuclear accidents. The video concludes with practice problems to reinforce learning.
