SUMMARY
The discussion centers on the decay process of Molybdenum-99 (Mo-99) into Technetium-99m (Tc-99m) through beta decay. In this process, one neutron in the Mo-99 nucleus, which consists of 42 protons and 57 neutrons, transforms into a proton by expelling an electron. This results in the formation of Tc-99m, characterized by 43 protons and 56 neutrons, which exists in a meta-stable state before decaying into stable Technetium-99 (Tc-99) by emitting a gamma ray photon. Tc-99m has a half-life of approximately 6 hours, while Tc-99 has a significantly longer half-life of over 210,000 years.
