The name of radioactive nuclide I chose to look up is Technetium-99 (Tc=99). There are two forms of technetium being technetium-99 and technetium-99m, which is a short-lived form of Tc-99 (EPA.gov, 2017). Technetium-99 emits beta particles. Below is an equation showing the decay of technetium.
99 0 99 Tc = B + Ru 43 -1 44
Technetium-99 has a half-life of over 200,000 years while the United States Environment Protection Agency describes technetium-99m as, “Having short half-life (6 hours) and does not remain in the body of environment for long.” Technetium is found in the environment from air, waters, soils, plans and animals and is used for medical diagnostic test (technetium-99m)
