In many cases, prostate cancer is treated by implanting 60 to 100 small seeds of radioactive material into the tumor. The energy released from the decays kills the tumor. One isotope that is used (there are others) is palladium (103Pd) with a half-life of 17 days. If a typical grain contain 0.27 g of 103Pd, (a) what is its initial activity in Bq and (b) what is the activity 68 days later?
A patient receives a dose of radiation by ingesting a radioactive medication containing 32P, which emits B rays with an RBE of 1.5. The energy of each emitted B is 705 keV. The half-life of 32p is 14.28 days, and the initial activity of the medication is 1.34 MBq.

The decay chain of uranium includes radon, a noble gas. When uranium in the soil decays to radon, it may seep into houses; this can be a significant source of radiation exposure. Most of the exposure comes from the decay products of radon, but some comes from alpha decay of the radon itself. If radon in the air in your home is at the maximum permissible level, the gas in your lungs will have an activity of about 0.22 Bq. Each decay generates an alpha particle with 5.5 MeV of energy, and essentially all that energy is deposited in lung tissue. Part A Over the course of 1 year, what will be the dose equivalent in Sv to the approximately 0.90 kg mass of your lungs? Express your answer in millisieverts per year.
