Nuclear Fallout

SOURCE A nuclear explosion Vaporizes any material within the Fireball , including the ground if it is nearby, and this is combined with residual Ionizing Radiation to produce fallout. Fission byproducts Fission products are intermediate weight Isotope s which are formed when a heavy Uranium or Plutonium Nucleus is split in a fission reaction. There are over 300 different fission products that may result from a fission reaction. Many of these are radioactive with widely differing Half-lives . Some are very short (fractions of a second) while a few are long enough that the materials can be a hazard for months or years. Their principal mode of decay is by the emission of Beta Radiation , usually accompanied with Gamma Radiation . Approximately 60 G of fission products are formed per Kiloton of yield. The estimated activity of this quantity of fission products 1 minute after detonation is 1.1 ZBq , equal to that of 30 Gg of Radium , in equilibrium with its Decay Product s. The mixture of fission product Radioisotope s is very complex.
