Spaltstoffe — analyse des gefährdungspotentials

Abstract

The hazard potential of fissile material — especially of plutonium — is increasingly discussed in the public. This essay tries to point out the real hazards originating from the existence and use of fissile nuclides. As an introduction the main properties of the different fissile materials and the nuclear data of the uranium and plutonium isotopes are listed. The special nuclear properties that initiate potential hazards are the radioactivity and the fission process. They generate the possibility of irradiation from outside, of incorporation of radioactive nuclides, and of energy and radiation release in the course of a critical accident. The danger and consequences of such occurrences are evaluated to some details. Finally, the possible misuse of fissile materials in the hands of terrorists are adressed as well as the worldwide threat by the existence of nuclear weapons.
