If you started with 100 million radioactive atoms, how many would you have left after: a. One half-life: 100 million/2 = 50 million b. Radon-222 is a radioactive gas with a half-life of 3.82 days. How long will it take for 15/16 of a sample Radon-222 to decay? 2015-08-13 The half life of Radon-222 is 4 days. Using this example, explain what half life is. Be specific.
