Findings and Purpose of Title V of Pub. L. 104–132 Relating to Nuclear Materials
Pub. L. 104–132, title V, §501, Apr. 24, 1996, 110 Stat. 1281, provided that:
"(a)
"(1) nuclear materials, including byproduct materials, can be used to create radioactive dispersal devices that are capable of causing serious bodily injury as well as substantial damage to property and to the environment;
"(2) the potential use of nuclear materials, including byproduct materials, enhances the threat posed by terrorist activities and thereby has a greater effect on the security interests of the United States;
"(3) due to the widespread hazards presented by the threat of nuclear contamination, as well as nuclear bombs, the United States has a strong interest in ensuring that persons who are engaged in the illegal acquisition and use of nuclear materials, including byproduct materials, are prosecuted for their offenses;
"(4) the threat that nuclear materials will be obtained and used by terrorist and other criminal organizations has increased substantially since the enactment in 1982 of the legislation that implemented the Convention on the Physical Protection of Nuclear Material, codified at section 831 of title 18, United States Code;
"(5) the successful efforts to obtain agreements from other countries to dismantle nuclear weapons have resulted in increased packaging and transportation of nuclear materials, thereby decreasing the security of such materials by increasing the opportunity for unlawful diversion and theft;
"(6) the trafficking in the relatively more common, commercially available, and usable nuclear and byproduct materials creates the potential for significant loss of life and environmental damage;
"(7) report trafficking incidents in the early 1990's suggest that the individuals involved in trafficking in these materials from Eurasia and Eastern Europe frequently conducted their black market sales of these materials within the Federal Republic of Germany, the Baltic States, the former Soviet Union, Central Europe, and to a lesser extent in the Middle European countries;
"(8) the international community has become increasingly concerned over the illegal possession of nuclear and nuclear byproduct materials;
"(9) the potentially disastrous ramifications of increased access to nuclear and nuclear byproduct materials pose such a significant threat that the United States must use all lawful methods available to combat the illegal use of such materials;
"(10) the United States has an interest in encouraging United States corporations to do business in the countries that comprised the former Soviet Union, and in other developing democracies;
"(11) protection of such United States corporations from threats created by the unlawful use of nuclear materials is important to the success of the effort to encourage business ventures in these countries, and to further the foreign relations and commerce of the United States;
"(12) the nature of nuclear contamination is such that it may affect the health, environment, and property of United States nationals even if the acts that constitute the illegal activity occur outside the territory of the United States, and are primarily directed toward foreign nationals; and
"(13) there is presently no Federal criminal statute that provides adequate protection to United States interests from nonweapons grade, yet hazardous radioactive material, and from the illegal diversion of nuclear materials that are held for other than peaceful purposes.
