D 12.4.2 4) Find the Radon LevelRadon can pose a health risk when high levels become trapped in the basement of a house. Testkits are used by homeowners to monitor the radiation level. Suppose 3.38 x 107 radon atoms arein a basement at a time when it is sealed to prevent any additional radon from entering. Given thatthe decay constant of radon is 0.181 d', how many radon atoms remain in the basement after (a)7 d and (b) 14 d? 9.52 x06 atoms, 2.68×106 atoms

To find out how many radon atoms remain in the basement after a certain number of days, we can use…
