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...

All radioactive decay processes follow first-order kinetics. The half-life of a gamma producing radioactive isotope is 2.4 hours. This isotope is used in a medical scan and enough of the isotope is given such that a heart scan can be done? If 0.75 ng of the isotope is administered, how ng of the isotope remains in the patient after 3.5 days?
