A radioactive isotope of phosphorus, 32P, is used in internal radiotherapy to treat patients with cancers and other diseases of the bone marrow. 32P has a half-life of 14.28 days and a atomic mass of 32P is 31.973 u. Via β decay, it emits an electron with an energy of 705 KeV and a RBE of 15.5 . As part of a treatment program, a patient ingests a radioactive pharmaceutical containing 32P which has an initial activity of 1.33 MBq....

Gallium 67 (67Ga) is a radioactive isotope with a half-life of 3.26 days. It's used in nuclear medicine to locate inflammations and tumors. Accumulations of 67 Ga in a patient's tissue can be detected by looking for the gamma rays it emits when it decays. 3 days after 67Ga was administered to the patient, what fraction of the 67Ga nuclei remains?

Gallium 67 (67Ga) is a radioactive isotope with a half-life of 3.26 days. It’s used in nuclear medicine to locate inflammations and tumors. Accumulations of 67Ga in a patient’s tissue can be detected by looking for the gamma rays it emits when it decays. A radiologist usually begins looking for the 67Ga about 52 hours after administering it to a patient. What fraction of the original 67Ga nuclei remains after 52 hours? **Please solve using half life equation formula, you...
