Radon is the number one hazard in the home. Appearance and Characteristics Harmful effects: Radon is highly radioactive and a carcinogen. Its decay products are toxic and radioactive. Radon is present in most homes and is the number one cause of lung-cancer in non-smokers in the USA. (See...
“Radon is the number 1 cause of lung cancer amongst non-smokers.” In the air, radon breaks down into tiny radioactive elements (radon progeny) that can lodge in the lining of the lungs, where they can give off radiation. This radiation can damage lung cells and eventually lead to lung...

Chapter 4/ Lesson 5 84K Nuclear chemistry is the science of using radioactive isotopes and other nuclear reactions to diagnose and treat medical conditions and also to determine the age of artifacts through a process called carbon dating. Learn about nuclear fusion, nuclear fission, tracers, imagi...
indicating collective behaviour of the nucleons. However, the number of observed cases where the correlations are strong enough to induce a static pear-shape is much smaller. Strong evidence for this type of deformation comes from the observation of a particular behaviour of the energy levels for...
