4) Find the Radon Level Radon can pose a health risk when high levels become trapped in the basement of a house. Test kits are used by homeowners to monitor the radiation level. Suppose 3.38 x 107 radon atoms are in a basement at a time when it is sealed to prevent any additional radon from entering. Given that the 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
