Radiation hazard and protection for the nuclear weapon terrorism

摘要

The possibility of nuclear weapon attack by terrorists (NWAT) occurring after September 11th 2001 may be considered as the most dangerous radiation hazard in the 21st century [1]. It is difficult for us to believe that the risk of nuclear attack, unrelated to war, may occur in a city of a developed nation. Emergency measures for radiation protection are one of the main topics regarding nuclear terrorism.For a 3-year period, we especially focused on the assessment of hazard and radiation protection in case of a terrorist attack with nuclear weapons. We studied field investigations of ground zero (GZ) of small weapons in Semipalatinsk Nuclear Test Site (SNTS). Here, we report dose fore-assessment and propose a method of radiation protection in case of 1 kt NWAT in a city.
