Radium Isotope Ra-226 a) Fully show the decay scheme of this isotope as it is transformed into radon Rn-222 via two different routes. A needle contains 1 mg of radium. Find the decay constant and the activity in Bq of this isotope, given that its half-life is 1620 years and Avogadro's number is 6.02 x 1023. c) b) If 1 mg of radium decays for 1 day, how many 0.18 MeV gamma rays will be emitted?
