220 Rn k2 216 Po 224 Ra (a) Determine the time after the introduction of Radium in a room at which the Radon concentration reaches a maximum. Values for the rate constants are k1=2.20x106 s and k2=1.26x102 s'. (b) If the initial concentration of Radium is 10 pCi/L, what is the maximum concentration of Radon that will built up? (Note that the EPA requires corrective if the Radon level exceeds 4 pCi/L.)
