Radon-220 (220Rn) is radioactive and decays via theersion of a high energy alpha particle into 216Po. It is dangerous because it is a noble gas and can be breathed in our lungs. This is a particular problem in the basement of homes that have been built in soil with a higher concentration of uranium, as it is a decay product of 238 U. Its decay constant is k = 0.0125 s ¹. If you were to breathe in a particle of dust to which 1.0 picogram of 220Rn was adsorbed, how many alpha particles would be striking the cells lining the surface of your lungs per second? Recall that the superscript on the atomic notation is its molar mass and pico is the prefix indicating 10-12. 3.42 x 107 5.68 x 10-17 0.0125 4.55 x 10-15 2.74 x 10⁹ 4.28 x 105
