. 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...

Radon is a colorless, odorless, radioactive noble gas. Because it occurs naturally in soil, it can become trapped in homes and buildings. Despite a short half-life of only 3.83 days, high concentrations of radon indoors can pose a risk of lung cancer. (For this reason, many modern homes and buildings have radon reduction systems installed.) Consider an enclosed space in a building which contains 3.30 g of radon gas at time t = 0. What mass of radon (in g)...
