“Belgian police, while searching the home of an Islamic State or ISIS suspect after the Paris bombings last year, found surveillance films taken of a senior researcher at a Belgian nuclear center, which produces a significant portion of the world’s radioisotopes, and his family. Police suspect ISIS terrorists wanted to capture the man or his family members and hold them for ransom in exchange for nuclear materials.
“We can imagine that the terrorists might want to kidnap someone or kidnap his family,” so they can force their target to turn over the radioactive innards of such a device after removing the materials surreptitiously, said Nele Scheerlinck, a spokeswoman for Belgium’s Federal Agency for Nuclear Control, the nation’s nuclear regulator, NBC News reported.
“We know that it would not require a team of nuclear physicists or even a particularly sophisticated criminal network to turn raw material into a deadly weapon,” an internal Energy Department report on the threat, designated “Official Use Only,” declared in May 2013. “In many cases, a determined lone wolf or a disgruntled insider is all it might take.””
