(b) If we have 500 mg of radium 222 Ra (parent atom) that is transformed into radon isotope 222 Rn (daughter atom), how much activity of 222Rn will be collected after 1 day, after 3.8 days, and after 100 days? The specific activity of radium is 3.7 x 100 Bq g- and the half-life of 222Ra and 222 Rn is 1600 years and 3.8 days, respectively.
