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 have to make all the units the same, convert years to hours. Answer should be in decimal form!!

Technetium 99m (99mTc) is a radioactive nucleus with a half-life of 6.03 hours. It’s used in nuclear medicine to trace biological pathways. The 99mTc nucleus is actually an excited state of the 99Tc nucleus, and the radiative transition 99mTc -> 99Tc emits a gamma ray. That gamma ray shows where the nucleus was located when it decayed. If the radiologist begins looking for 99mTc 3.42 hours after administering it, what fraction of the 99mTc nuclei remains? Please solve using half...

consider the transition metal gallium. The gallium-67 isotope (67Ga) is a radioactive element often used in hospitals to image inflammation and chronic infections via a technique called a gallium scan. 67Ga has a half-life equal to 3.3 days and decays to 67Zn via a process called electron capture, which follows first order kinetics. How long will it take for the amount of 67Ga in your sample to drop to 6.25%? a. 3.3 days b. 9.9 days c. 13.2 days d....

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?
