The radioactive residue of a nuclear device after it has been detonated, con isting of fission products, various products of neutron capture, weapon casing and other componen » and uranium or plutonium that has escaped fission. ahole body irradiation. Exposure of the body to ionizing radiation from external radiation urces. Critical organs for the whole body are the lens of the eye, the gonads, and the red-blood-fo ing marrow. As little as only 1 cm” of bone marrow constitutes a whole-body exposure. Thus, the en ire body need not be exposed to be classed as a whole-body exposure, Wilson.

Open lighter (nonself-propelled; Navy). Covered lighter (nonself-propelled; Navy). yield. The total effective energy released in a nuclear detonation. It is usually expressed in terms of the equivalent tonnage of TNT required to produce the same energy release in an explosiorg. The tota] energy yield is manifested as nuclear radiation (including residual radiation}, thermal 4 Adiation, and blast and shock energy, the actual distribution depending upon the medium in which th Pp explosion occurs and also upon the type of weapon. See TNT equivalent. yield (blast). That portion of the total energy of a nuclear detonation that is identified ag the blast or shock wave. vield (fission}, That portion of the total explosive yield attributable to nuclear fission, opposed to fuston. fhe interest in fission yield stems from the interest in fission preaduct formati no and its relationship ta radioactive fallout.
