Q: Question is on the picture. It's IB Physics SL, so I wasn't sure what category to put it in.
A:
A 14-gram ovarian tumor is treated using a sodium phosphate solution in which the phosphorus atoms are the radioactive Phosphorus-32 isotope with a half-life of 14. 3 days and which decays via beta emission (RBE=1) with an energy of 1.71MeV. Half of the sodium phosphate solution is absorbed by the tumor and deposits 9.0 J of energy into it. The other half of the solution is dispersed throughout the patient’s tissues, also depositing 9.0 J of energy into the 50.0 kg of body tissues.
