    "en": "Nuclear agents are derived from neutron radiation (n) which is a neutron emitted by an unstable nucleus, in particular during atomic fission and nuclear fusion. Apart from a component in cosmic rays, neutrons are usually produced artificially. Because they are electrically neutral particles, neutrons can be very penetrating and when they interact with matter or tissue, they cause the emission of beta- and gamma-radiation. Neutron radiation therefore requires heavy shielding to reduce exposure (IAEA, 2004). <br /> <p>IAEA, 2004. <a href=\"https://www.iaea.org/sites/default/files/radiation0204.pdf\">Radiation, People and the Environment.

      "Dispersal of neutron radiation through nuclear weapons, including improvised nuclear devices (IND) results in a nuclear yield unlike radiation dispersal devices (RDD). This nuclear yield is measured in kilotons (kT) and one unit has the explosive energy equivalent to a thousand tons of TNT. Nuclear detonations are capable of producing impacts far surpassing that of any conventional explosive (IAEA, 2004). A significant effect of a nuclear explosion is the blast generated. The blast originates from the rapidly expanding fireball of the explosion, which generates a pressure wave moving rapidly away from the point of detonation. Initially, near the point of detonation (also referred to as ‘ground zero’) for a surface nuclear burst, the overpressure is extremely high. With increasing distance from ground zero, the overpressure and speed of the blast wave dissipate to a point at which they cease to be destructive. In the case of a nuclear terrorism incident, the thermal pulse can cause skin burns on those people within a few miles of the incident who have a line-of-sight view of the fireball (IAEA, 2004). There will be many hazards after a nuclear terrorism incident, including widespread fires and the presence of toxic materials, but one of the most significant in terms of human health for a ground level or near ground level nuclear incident, will be the residual radiation from radioactive fallout and neutron activation of materials. Although the radiation levels are most hazardous in the first few hours, some areas within a few miles downwind may still be hazardous days after the incident. Rapid identification of these fallout areas for implementation of protective measures is one of the highest priorities for emergency management and public health authorities (IAEA, 2004)."
