Question

41. A patient receives 3.0 mL of a solution containing technetium-99m for a breast image. If the activity of the technetium-99m is 9.5 mCi/mL, what is the dose received by the patient? A) 3.2 mCi B) 29 mCi C) 320 μCi D) 9.5 mCi E) 28.5 mCi 42. When an atom of uranium-235 is bombarded with neutrons, it splits into smaller nuclei and produces a great amount of energy. This nuclear process is called A) fission B) fusion C) decomposition D) chain reaction E) ionization

Answer 1

Solution aam Volume of solution containing, technetium-99m = 3-oml Activity of technetium 9.5mCi/mL '' an ml solution, technetium-qam dose received by patient = 9.5mci .: 9n 3.0ml solution, technetium-99m dose received by patient = 9.5mci XBom. ImL = 28.50mci Ans:- Dose received by patient is 28.5 mci © Q When an atem of uranium-235 is Gombarded with neutrous, it splits into smaller nuclei and produces a great amount This nuclear process is called chain reaction of energy Ans:- Chain reaction CS Scanned with CamScanner
