The threat of terrorists acquiring HUE has been exaggerated. Any uranium with more than a 20% concentration of uranium-235 is considered highly enriched. Nuclear power plants use uranium enriched to 1%-5%.
Theoretically, uranium enriched to 30% or 40% could be used to make nuclear weapons, but it would take at least several hundred kilos of this kind of uranium to make a bomb. This is hardly a weapon terrorists could use. The bomb that destroyed Hiroshima in Japan had approximately 60 kilograms of HEU. Weapons-grade uranium is enriched to about 90%.
But a "dirty bomb" is quite another matter. It combines radioactive material (low- or medium-enriched uranium)
