150-water is a radioactive variation of regular water, in which some usual oxygen atoms are replaced by positron-emitting150. This liquid is used in positron emission tomography. The half-life of 150 is 122 seconds. Consider a patient whoreceived a sample of 150-water with an activity of 1.2 mCi. Determine the activity of the sample in the patient's bodyafter 18 minutes has passed, if no 150-water has left the patient's body in this time.OA. 2.2 μCiOB. 2.6 μCiOC. 2.2 mCiOD. 1.1 mCi The radioactive isotope of rubidium 82Rb is widely used in myocardial perfusion imaging. 82Rb has a very short half-life (1.27 minutes), so it is produced from its parent nucleus 825r at the medical facilities. The settings for the production of82Rb are known as strontium-rubidium generators. The half-life of 825r is 25.36 days, so 825r should be supplied tomedical facilities on a monthly base. The initial activity of 825r in the generator was 2.8 MBq. Determine the activity ofstrontium in the generator after 20 days of usage.OA. 34 µCiB. 15.6 µCiOC. 43.8 µCiOD. 1.62 µCi
