4. Thorium-229 is used in cancer treatment. It has a half-life of 7340 years. a) What type of radioactive decay would you expect Thorium-229 to undergo? Explain your answer in 1-2 sentences. b) Write a balanced nuclear reaction for the decay that you predicted in part a. c) Suppose a patient is given 15.0 pg of Th-229 for cancer treatment. What is the activity of this Th- 229 in Ci? d) If the patient in part c) weighs 65 kg, what dose of radiation do they receive (in rem) from the Th- 229 over the course of one day? Assume that each decay event produces 8.01 x 1013 Jof energy and that the R.B.E. is 20.
