Radon-222 (222 86 Rn) is a radioactive gas that is often found in homes as a byproduct of natural radiation in the ground. It has a mass of 222.017578u and a half-life of 3.8235 days. You are conducting an experiment on the effects of Radon on bacteria. You begin the experiment at 8:00 am on Monday when you introduce 4.00 µg of Radon-222. Later in the week you are concerned that the activity is too low for your experiment. How...

. Of much concern to environmentalists is radon-222, which is a radioactive noble gas that can seep from the ground into basements of homes and buildings. Radon-222 is a product of the decay of radium-226 that occurs naturally in rocks and soil in much of the United States. Radon-222, which has a half-life of 3.8 days, decays by emitting an alpha particle. Radon-222, which is a gas, can be inhaled into the lungs where it is strongly associated with lung...
