"Since 2004, NNSA's Second Line of Defense -- SLD -- program has assisted the Cyprus Customs Service in maintaining radiation detection equipment by providing new equipment and training that improves detection of nuclear and radioactive material in cargo at the port," the agency said.

NNSA said its SLD program "provides detection systems around the world to help combat nuclear proliferation and terrorism. SLD installs radiation detection equipment at strategic locations, and provides training in detection, identification, and interdiction of nuclear and radiological materials, as well as training in the operations and maintenance of the equipment."

"The specialized radiation-detection technology is part of the overall U.S. nuclear security program to guard against proliferation of weapons materials. It is part of the Bush administration's overall efforts in preventing the proliferation of weapons of mass destruction," the agency said.
