Chapter 8 Nuclear Chemistry

Chapter 8 Nuclear Chemistry. Radiation. The emission of energetic particles The study of radiation and the processes that produce it is called nuclear chemistry. Unlike the chemistry we have studied to this point, nuclear chemistry often results in one element changing into another one.

Radon

Radon. By: Austin. What is radon?. Radon is a cancer-causing radioactive gas. You cannot see, smell or taste radon, but it may be a problem in your home. The Surgeon General has warned that radon is the second leading cause of lung cancer in the United States today.

What it is, how it affects us, why it matters?

The U.S. Environmental Protection Agency (US EPA) and the Surgeon Generalu2019s Office have estimated that as many as 20,000 lung cancer deaths are caused each year by radon. Radon is the second leading cause of lung cancer. Radon-induced lung cancer costs the United States over $2 billion dollars per year in both direct and indirect health care costs.
