Physics The first isotope used in radioactive therapies was 88RA 226 (226.0254u), which decays to 86RN 222 (222.0175u). a) (2) What is the type of decay? b) (8) Determine the amount of energy released in this decay. c) (10) If a 2ugram sample of 88RA 226 that has a half-life of 1622 years is used, how many disintegrations happen each second? (Note: the mole mass of 88RA 226 is 226grams) Physics The first isotope used in radioactive therapies was 88RA 226 (226.0254u), which decays to 86RN 222 (222.0175u). a) (2) What is the type of decay? b) (8) Determine the amount of energy released in this decay. c) (10) If a 2ugram sample of 88RA 226 that has a half-life of 1622 years is used, how many disintegrations happen each second?
