<Li> Ionizing radiation--5% of total energy (more in a neutron bomb) </Li> <Li> Residual radiation--5--10% of total energy with the mass of the explosion </Li> <P> Depending on the design of the weapon and the environment in which it is detonated the energy distributed to these categories can be increased or decreased . The blast effect is created by the coupling of immense amounts of energy, spanning the electromagnetic spectrum, with the surroundings . Locations such as submarine, ground burst, air burst, or exo - atmospheric determine how much energy is produced as blast and how much as radiation . In general, denser media around the bomb, like water, absorb more energy, and create more powerful shockwaves while at the same time limiting the area of its effect . </P> <P> When an air burst occurs, lethal blast and thermal effects proportionally scale much more rapidly than lethal radiation effects, as higher and higher yield nuclear weapons are used . </P>
