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...
