1. If the HVL of lead for 60Co is 0.49 inches, what thickness of lead would be required to reduce 600 mrem/h of radiation to 2 mrem/h? [Note: A rule of thumb is that it takes 2 inches of lead to reduce the dose rate by a factor of 10.] 2. If the HVL of concrete for 60Co = is 2.6 inches, what thickness of concrete would be required to reduce 600 mrem/h of radiation to 2 mrem/h? 3. Calculate the activity remaining in a vial that originally contained 5 mCi of 32P three weeks ago. None of the sample has been extracted. [Note: 3 weeks equals 7 days; t0.5 for 32P = 14.3 days.]
