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...

Phosphorus-32 (P-32) is used in nuclear medicine as therapeutic
agent in the treatment of several diseases. P-32 has a half life of
14.3 days and decays directly to its ground state by emitting a
beta-minus particle. The decay table for P-32 is given. There are
no excited energy states or other radiation emitted during this
decay; therefore, P-32 is referred to as a "pure beta emitter.
A P-32 sample is prepared in the manufacturing site with
an initial activity of...

Thorium 230 itself is also radioactive and decays to Radium-226 with a half-life of γ and γ > τ Although Radium-226 is also radioactive its half-life is much longer than T and γ and here we assume that it is relative stable. Consider the scenario when we start with a certain amount of pure Uranium-234, because of this chain of decays, we...
