Because of his failure with New Coke, Coca-Cola Classic was born. Without the first failure, there would not have been the great success of the new campaign. You see, God can turn your failures into ultimate success. He can turn your test into a testimony; your mess into a message.
Gamma decay occurs when the nucleus undergoes an energy state change without actually changing the number or ratio of nucleons. . Technetium-99m (99mTc) is an example of such an atom. Its nucleus is the isomer of Technetium-99 (99Tc), and as an isomer, Technetium-99m rests at a higher energy state than the ground state Technetium-99.
Other sources of gamma-rays are alpha decay and gamma decay. Alpha decay occurs when a heavy nucleus gives off a helium-4 nucleus, reducing its atomic number by 2 and its atomic weight by 4. This process can leave the nucleus with excess energy, which is emitted in the form of a gamma-ray.
