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.
Quick Answer. Gamma rays are dangerous because they cause cellular damage that leads to DNA damage, cancer and radiation sickness. Because gamma rays are such a high-intensity, ionizing form of radiation, they pass through normal protections, such as skin, clothing, foil and goggles. Only high-mass shielding, such as lead, can stop them. Keep Learning.
