Q#2: What is the half-life of technetium-99m in minutes?
Hours?
Technetium (chemical symbol Tc) is a silver-gray, radioactive metal. It occurs naturally in very small amounts in the earth's crust, but is primarily man- made. Technetium-99 is produced during nuclear reactor operation, and is a byproduct of nuclear weapons explosions. Technetium-99 can be found as a component of nuclear waste. Technetium-99m is a short-lived form of Tc-99 that is used as a medical diagnostic tool. As this isotope decays, it...
