Isotopes 133I55 experiences β- decay with half-life T=20.8 hr and transform into 133Xe54 which in its turn decays with T=5.27 days, changing into 133Cs55. The activity of calcium iodate CaI2 measured in 24 hours after its production is 1020 Bq. Supposing that at the initial point Xe was absent, determine the initial quantity of CaI2
