The most stable isotope of astatine is At-210, which has a half-life of about 8.1 hours. This isotope's primary decay mode is positron emission to the relatively long-lived alpha emitter, polonium-210. In total, only five isotopes of astatine have half-lives exceeding one hour: those between 207 and 211.
Technetium -99m is a widely used radioactive tracer isotope in Nuclear Medicine.It's gamma ray energy of about 140 keV is convenient for detection. The fact that both its physical half-life and its biological half-life are very short leads to very fast clearing from the body after an imaging process.echnetium -99m is a widely used radioactive tracer isotope in Nuclear Medicine.
